Troparion for Pachomius the Great (Tone VII)
With the streams of thy tears thou didst irrigate the barren desert,
and with sighs from the depths of thy soul thou didst render thy labors fruitful an hundredfold.
Thou wast a beacon for the whole world, radiating miracles.
O our father Pachomius, entreat Christ God that our souls be saved.
