5 When Lamech had lived a hundred and eighty-two years, he became the father of a son, and called his name Noah, saying, "Out of the ground which the LORD has cursed this one shall bring us relief from our work and from the toil of our hands," Lamech lived after the birth of Noah five hundred and ninety-five years, and had other sons and daughters. Thus all the days of Lamech were seven hundred and seventy-seven years; and he died. After Noah was five hundred years old, Noah became the father of Shem, Ham, and Japeth.
6 When men began to multiply on the face of the ground, and daughters were born to them, the sons of God saw that they were fair; and they took to wife such of them as they chose. Then the LORD said, "My spirit shall not abide in man for ever, for he is flesh, but his days shall be a hundred and twenty years." The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. These were mighty men that were of old, the men of renown. The LORD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And the LORD was sorry that he had made man on the earth, and it grieved him to his heart. So the LORD said, "I will blot out man whom I have created from the face of the ground, man and beast, and creeping things of the air, for I am sorry that I have made them." But Noah found favor in the eyes of the LORD. These are the generations of Noah. Noah was a righteous man, blameless in his generation; Noah walked with God. And Noah had three sons, Shem, Ham and Japheth. Now the earth was corrupt in God's sight, and the earth was filled with violence. And God saw the earth, and behold, it was corrupt; for all flesh had corrupted their way upon the earth. and God said to Noah, "I have determined to make an end of all flesh; for the earth is filled with violence through them; behold, I will destroy them with the earth. Make yourself an ark of gopher wood; make rooms in the ark, and cover it inside and out with pitch. This is how you are to make it: the length of the ark three hundred cubits, its breadth fifty cubits, and its height thirty cubits. Make a roof for the ark, and finish it to a cubit above; and set the door of the ark in its sice; make it with the lower, secon, and third decks. For behold, I will bring a flood of waters upon the earth, to destroy all flesh in which is the breath of life from under heaven; evrything that is on the earth shall die. But I will establish my covenant with you; and you shall come into the ark, you, your sons, your wife, and your son's wives with you. And every living thing of all flesh, you shall bring two of every sort into the ark, to keep them alive with you; they shall be male and female. Of the birds according to their kinds, and of the animals according to their kinds, of every creeping thing of the ground according to its kind, two of every sort shall come in to you, to keep them alive. Also take with you evrey sort of food that is eaten, and store it up; and it shall serve as food for you and for them.: Noah did this; he did all that God commanded him.
7 Then the LORD said to Noah, "Go into the ark, you and all your househol, for I have seen that you are righteoous before me in this generation. Take with you seven pairs of all clean animals, the male and his mate; and a pair of the animals that are not clean, the pair and his mate; and seven pairs of the birds of the air also, male and female, to keep their kind alive upon the face of the earth. For in seven days I will send rain upon the earth forty days and forty nights; and every living thing that I have made I will blot out from the face of the ground." And Noah did all that the LORD had commanded him. Noah was six hundreed years old when the flood waters came upon the earth. And Noah and his sons and his wife and his son's wives with him went into the ark, to escape the waters of the flood. Of the clean animals, and of animals that are not clean, and of birds, and of everything that creeps on the ground, two by two, male and female, went into the ark with Noah, as God had commanded Noah. And after seven days the waters of the flood came upon the earth. In the sixth hundredth year of Noah's life, in the second month, on the seventeeth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened. And rain fell upon the earth forty days and forty nights. On the very same day Noah and his sons, Shem, Ham, and Japheth and Noah's wife and the three wives of his son's with them entered the ark, they and every beast according to its kind, and all the cattle according to their kinds, and every creeping thing that creeps on the earth according to its kind, and every bird according to its kind, every bird of every sort. They went into the ark with Noah, two and two of all flesh in which there was the breath of life. And they that entered, male and female of all flesh, went in as God commanded him; and the LORD shut him in. The flood continued forty days upon the earth; and the waters increased, and bore up the ark, and it rose high above the earth. The waters prevailed and increased greatly upon the earth; and the ark floated on the face of the waters. And the waters prevailed so mightily upon the earth that all the high mountains under the whole heaven were covered; the waters prevailed above the mountains, covering them fifteen cubits deep. And all flesh died that moved upon the earth, birds, cattle, beasts, all swarming creatures that swarm upon the earth, and every man; everything on the dry land in whose nostrils was the breath of life died. He blotted out every living thing that was upon the face of the ground, man and animals and creeping things and birds of the air; they were blotted out from the earth. Only Noah was left, and those that were with him in the ark. And the waters prevailed upon the earth a hundred and fifty days.
8 But God remembered Noah and all the beasts and all the cattle that were with him in the ark. And God made a wind to blow over the earth, and the waters subsided; the fountains of the deep and the windows of the heavens closed, the rain from the heavens restrained, and the waters receded from the earth continually. At the end of a hundred and fifty days the waters had abated; and in the seventh month, on the seventeenth day of the month, the ark came to rest on mountains of Ararat. And the waters continued to abate until the tenth month, on the first day of the month, the tops of the mountains were seen. At the end of the forty days Noah opened the window of the ark which he had made, and sent forth a raven; and it went to and for until the waters fried up fron the earth. The he sent forth a dove from him, to see if the waters had subsided from the face of the ground; but the dove found no place to set her foot, and she returned to the ark, for the wates were still on the face of the whole earth. So he put forth his hand and took her and brought her into the ark with him. He waited another seven days, and again he sent forth another dove out of the ark; and the dove came back to him in the evening, and lo, in her outh a freshly plucked olive leaf; so Noah knew that the waters had subsided from the earth. Then he waited another seven days, and sent forth the dove; and she did not return to him anymore. In the six hundred and first year, in the first month, the first day of the month, the waters were dried from off the earth; Noah removed the covering of the ark, and looked, and behold the face of the ground was dry. In the second month, on the twenty-seventh day of the month, the earth was dry. Then God said to Noah, "Go forth from the ark, you and your sons and your son's wives with you. Bring forth with you every living thing that is with you of all flesh-birds and animals and every creeping thing that creeps on the earth, and be fruitful and multilply upon the earth." So Noah went forth, and his sons and his wife and his son's wives with him. And every beast, every creeping thing, and every bird, everything that moves upon the earth, went forth by families out of the ark. then Noah built an altar to the LORD, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar. And when the LORD smeeled the pleasing odor, the LORD said in his heart, "I will never again curse the ground because of man, for the imagination of man's heart is evil from his youth; neither will I ever again destroy every living creature as I have done. While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease."
9 And God blessed Noah and his sons and said to them, "Be fruitfull and multiply, and fill the earth. The fear of you and the dread of you shall be upon every beast of the earth and bird of the air, upon everything that creeps on the ground and all the fish of the sea; into your hand shall they be delivered. Every moving thing that lives shall be food for you; and as I gave you the green plants, I give you everything. Only you shall not eat flesh with its life, that is, its blood. For your lifeblood I will surely require a reckoning; of every beast I will require it and of man; of every man's brother I will require the life of man. Whoever sheds the blood of man, by man shall his blood be shed; for God made man in his own image. And you, be fruitful and multiply, bring forth abundantly on the earth and multiply in it." Then God said to Noah and to his sons with him, "Behold, I establish my covenant with you and your descendants after you, and with every living creature that is with you, the birds, the cattle, and every beast of the earth with you, as many as came out of the ark. I establish my covenant with you, that never again shall all flesh be cut off by the waters of a flood, and never again shall there be a flood to destory the earth." And God said, "This is the sign of the covenant which I make between me and you and every living creature that is with you, for all future generations: I set my bow in the cloud, and it shall be a sign of the covenant between me and the earth. When I bring clouds over the earth and the bow is seen in the clouds, I will remember my covenant which is between me and you and every living creature of all flesh; and the waters shall never again become become a flood to destroy all flesh. When the bow is in the clouds, I will look upon it and remember the everlasting covenant between God and every living creature of all flesh that is upon the earth." God said to Noah, "This is the sign of the covenant which I have established between me and all flesh that is upon the earth."
The Life of Noah and His Children After the Flood.
By Orthodoxphotos.com  The sons of Noah who emerged with him from the ark were Shem, Ham and Japheth.
Noah began to work the earth and planted a vineyard. When he had made wine of the juice of the vine and had drunk it, he became intoxicated because he did not know as yet the strength of wine, and taking his clothes off, he lay naked in his tent. His son Ham, the father of Canaan, saw this. He acted without proper respect for his father and told his brothers about this. Shem and Japheth, however, took clothing, and came up to their father in such a way as not to see his nakedness and covered him. When Noah woke up and learned about the action of the youngest son, Ham, he condemned and cursed him in the person of his son Canaan, and said that his offspring would be in slavery to the offspring of his brothers. But Shem and Japheth he blessed and prophesied that the true faith would be preserved in the offspring of Shem, and the offspring of Japheth would spread across the earth and accept the true faith from the offspring of Shem.
Noah lived for 950 years. He was the last to live to such an advanced age. After him, the strength of the human race began to decline, and people could live for only 400 years. But even with this length of life, the population increased.
All that Noah foretold his sons was fulfilled precisely. The offspring of Shem are called the Semites, to whom there belong firstly the Hebrew people, with whom faith in the true God was preserved. The offspring of Japheth are called Japhethites, to whom there belong the peoples that populated Europe and Asia, who accepted faith in the true God from the Hebrews. The offspring of Ham are called Hamites. The Canaanite tribes which originally inhabited Palestine, and were later subjugated by the offspring of Shem and Japheth, belong to them.

The human race began to multiply very rapidly from the children of Adam and Eve. At that time people lived for a very long time, up to nine hundred years or more.
From Seth there came forth pious and good people, "sons of God," but from Cain, wicked and evil people, "sons of men," At first, the offspring of Seth lived separately from the offspring of Cain. They preserved faith in God and the coming Saviour. Later however, they began to take for themselves wives from the daughters of the offspring of Cain, and through them, began to adopt bad habits, to be corrupted, and to forget the true God.
After a considerable time, the wickedness of men was so great that, of all the people on earth, only one of the offspring of Seth remained faithful to God, the righteous Noah and his family.
Beholding the great corruption of mankind, the merciful Lord gave them 120 years for repentance and correction. But men not only did not correct themselves, they became even worse.
Then the Lord decided to cleanse the earth of the evil human race with water, but to preserve the righteous Noah and his family on the earth to continue the human race.
God said to Noah, "The end has come for all creatures, for the earth has been filled by them with evil works; and I shall obliterate them from the face of the earth. I shall bring upon the earth a flood of water to destroy all that is upon the earth" (Cf. Gen. 6:13-17). He commanded Noah to build an ark, a huge, rectangular vessel like a house, in which there would be room for his family and animals, and He gave him the precise measurements and directions for this. Noah accepted God’s commandment with faith and began to build the ark.
When the ark was ready, Noah, at the command of God, entered into it with his wife, his three sons and their wives, and at God’s direction, took with him all the animals and birds which could not live in the water: of the clean ones, that is, the ones which could be offered in sacrifice, seven pairs, and of the unclean ones, one pair, in order to preserve their kind upon the earth. He also took a reserve of food for them all for an entire year.
On that day when Noah entered into the ark, the waters of the flood gushed upon the earth, and "all the fountains of the great deep were broken up, and the windows of heaven were opened" (Gen. 7:11). There came about a mighty flood from the seas and oceans and from heaven rain poured down upon the earth for forty days and forty nights. The water rose over the earth higher than the highest mountains; it prevailed for 150 days and drowned all men and animals except the ones that were on the ark.
After 150 days the water began slowly to recede. In the seventh month the ark came to rest on the mountains of Ararat (in present day Turkey). On the first day of the tenth month the tops of the mountains appeared. After one year came to an end, the water receded into its proper place.
Noah opened a window in the ark and released a raven, in order to learn whether or not the water had receded from the earth, but the raven flew out and returned to the protection of the ark.
Then Noah released a dove which, when it had flown away, could not find a place to live, because the water was still over the heights of the entire earth, and it returned to the ark. After seven days, Noah again released the dove from the ark. This time the dove returned in the evening and brought a fresh olive leaf in its beak. Noah understood that the water had receded from the earth and that plants had appeared upon it. After waiting another seven days, Noah again released the dove, and this time it did not return to him. He opened the roof of the ark and beheld that the earth had dried.
Then, at the command of God, Noah went forth from the ark with all his family, and released all the animals that were with him.
Noah erected an altar, a place for offering sacrifices, and he offered for his salvation a sacrifice of thanksgiving to God from all the clean animals and birds. God mercifully accepted the sacrifice of Noah, blessed him and his sons, and promised that there would never again be such a flood to destroy all life on earth for the sins of men, that is, there would never again be a world-wide flood. As a sign of this promise, the Lord showed a rainbow in the clouds, which from that time has served as a faithful reminder to men of this promise of God.
Note: See Genesis, chaps. 4:17-24; 5; 6:1-22; 7; 8; 9:1-17.
Discussion of the Flood.
There is an objection to the story of the flood from those who do not believe. Some say that it would be impossible for the entire earth to be under water at the same time, as is recounted in the Bible. The flood may not have covered the entire earth. One must recall the purpose for which God made the flood: "God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually... So the Lord said, I will destroy man whom I have created from the face of the earth" (Gen. 6:5,7). Consequently, the flood can be imagined as covering only that part of the earth populated by sinful people, but how great an area this was at the time of the flood is entirely unknown to us. Moreover, the fact that the Bible speaks in several places of the flood extending over the entire earth need not disturb us. The Bible, and all religious literature which has as its purpose care for human souls, often calls an area of human habitation, or an isolated area of human habitation, or even just an isolated area of human civilization that has developed under the effect of Holy Scripture, "the earth," and even "the universe." Byzantium, which was nurtured on the Bible, called the Mediterranean basin "the universe;" and that is why she called her emperors "rulers of the universe," and why the Constantinopolitan Patriarch was given the title "ecumenical," or universal.
The widespread tradition of the flood testifies to its being an event that gripped all mankind, and that it was preserved in the memory of many branches of the human race. The same researcher, Arthur Hook, reports that the Chaldees, Phoenicians, Babylonians, Phrygians, Syrians, Persians, Greeks, and even the Armenians, all, to a greater or lesser degree, have mutually compatible accounts of the flood. The account of the Phrygians, for example, mentions Enoch as a prophet of the flood, and recounts that he wept and prayed over the fate of the hardened, unrepentant peoples of the antediluvian world. An ancient Phrygian coin was discovered with a wrought picture of the ark and the letters "N-O" on one side, which, undoubtedly refer to Noah. Further, we find that India and China have accounts of the flood, and that a certain person with the seven members of his family was saved from the flood. The Aztecs had a tradition about a man who made a vessel in order to save himself from a catastrophe that was about to occur.
In addition we should mention that on the basis of geological excavations, it is clear that there is in the earth a thick layer of clay, of alluvial deposits, which has no remains of organic animal life in it. This layer is sharply distinguished, and sharply divides the layers of the Paleolithic Age (Stone) from the later layers: neolithic, bronze and iron ages. The French scientist Mortilie called this layer Hiatus, that is, a break. It is assumed that this alluvial deposit came about from the depth of the sea with the action of a worldwide cataclysm; the land sank beneath the level of the ocean whose waters flooded the entire earth. Moses says of this, "and all the fountains of the great abyss were opened" (Gen. 7:11), and then he also speaks of rain. Furthermore, these alluvial deposits cover, in a thick layer, all Europe, North Africa and Western Asia to the highest peaks. The scientist Couvier called this sediment, this thick alluvial deposit, "Deluge."
by GOARCH  The Reading is from Matthew 24:36-51; 25:1-46; 26:1-2 The Lord said to his disciples, "Of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only. As were the days of Noah, so will be the coming of the Son of man. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they did not know until the flood came and swept them all away, so will be the coming of the Son of man. Then two men will be in the field; one is taken and one is left. Two of them will be grinding at the mill; one is taken and one is left. Watch therefore, for you do not know on what day your Lord is coming. But know this, that if the householder had known in what part of the night the thief was coming, he would have watched and would not have let his house be broken into. Therefore you also must be ready; for the Son of man is coming at an hour you do not expect.
