Venerable Mark, Jonah, and Bassa of the Pskov Caves - Troparion & Kontakion
Troparion — Tone 8
By a flood of tears you made the desert fertile, / and your longing for God brought forth fruits in abundance. / By the radiance of miracles you illumined the whole universe! / O our holy fathers Mark, Jonah, and Bassa, pray to Christ our God to save our souls!
