XIII. There once came thieves into an old man's cell, and said to him, "Whatever thou hast in thy cell, we have come to take away." And he said, "Take whatever you see, my sons." So they took whatever they could find in the cell, and went away. But they forgot a little bag that was hidden in the cell. So the old man, picking it up, followed after them, shouting and saying, "My sons, ye forgot this: take it." But they, marvelling at the patience of the old man, brought everything back into his cell, and they all did penance, saying one to another, "Truly, this is a man of God."
