Moses was an Ethiopian by birth. In the world, he was a thief and the leader of a band of thieves, and yet he became a penitent and a great ascetic. Moses was once a slave, who escaped and joined the thieves. Because of his great physical strength and daring, the robbers chose him as their leader. Then one day he was suddenly overcome with pangs of conscience and repented for his misdeeds. He left the thieves, entered a monastery, and gave himself over completely to obeying his spiritual father and the monastic rule. He benefited much from the teachings of Saints Macarius, Arsenius and Isidore. Later he withdrew to solitude in a cell, where he dedicated himself completely to physical labor, prayer, vigils and contemplating God. Tormented by the demon of lust, Moses confessed to Isidore, his spiritual father, who gave him counsel to increase his fasting, and even when eating to avoid satisfying his appetite. When this regimen did not help, he was counseled to keep all-night vigil and to pray standing. Then he also began the practice of bringing water to the elderly monks from a distant well, all night long. After six years of terrible struggles, St. Isidore miraculously healed him of lustful thoughts, fantasies and dreams perpetrated on him by the demon. Moses was ordained a priest in old age. He founded his own monastery, had seventy-five disciples, and lived to the age of seventy-five. He foresaw his death: one day he told his disciples to flee, for the barbarians were about to attack the monastery. When the disciples urged him to escape with them, Moses said that he had formerly been violent, and had to suffer violence himself, according to the words: For all they that take the sword shall perish with the sword (Matthew 26:52). He remained at the monastery with six brethren, and the barbarians slew them. One of the brethren, hiding nearby, saw seven shining wreaths descend from heaven upon the seven martyrs.
