The blessed Alexander brought his picked disciples across the Euphrates River, and off they went into the Persian Desert. With no garments to change into, nor any provision but the parchments of the holy Scriptures, they kept up their rule of singing hymns night and day without pause, and their stay in the desert went on and on.
At this time began a trial of the disciples' fleshly needs, that the worthiest among them might be revealed. They went for many days with nothing to eat but tree-nuts, and did not break ranks until some thirty of them began to mutter against the blessed one. Just as happened to Moses, they said to Alexander, "Have you led us into this desert to die of hunger?" This was premeditated, for their secret desire was to return to the monastery—as the blessed one well knew. Thanks to the intervention of the Holy Spirit, their desire could not be dissimulated from him, who was in truth a second Moses, faithful to God in all His house. Calling them to account, and addressing them like the faithless reprobates they were, he gave them leave to return to the monastery he had left behind, saying in a great voice: "Trust me, brothers, that the Lord watches over us, and will refute your lack of faith this very day."
They had gone but a short way when the holy man's words were fulfilled by God. For it was then that He caused a detachment of Roman tribunes and soldiers to come forth, loaded with goods on God's behalf, to summon the brothers to bless their fortifications. (Between the Roman and Persian terrirories there are fortifications set to hold off the barbarians, at a distance of ten or twenty mile-markers apart from each other.) Seeing them from afar, the deserting brothers realized that it was just as the divine father had spoken, and their faith was reinforced. Some of them fell on their faces in repentance, and rejoined the brothers. The rest went away to the inner desert, where they dwelled until the end of their lives.
