The [[Litany of Fervent Supplication]] (Slavonic: Ектенїѧ Сугубаѧ/Ekteniya Sugubaya) also sometimes ''Impetratory Litany, Augmented Litany, Fervent Litany''-- this litany is remarkable because of its fervency, indicated by the threefold response of the choir, "Lord, have mercy" (thrice). At the Divine Liturgy, this litany may also be augmented with special petitions, according to need as the pastor presiding clergyman sees fit.
