One night, Moses was attacked in his room by bandits. He overpowered the four men, tied them up and drug them to the chapel where he told his brothers that, "he didn't think that as a Christian he should hurt them -- but that he wasn't quite sure what to do with them." The four criminals were converted and also joined the desert community at Scetes.
When a fellow monk was charged with committing an infraction, a meeting was convened to decide on the appropriate punishment. Moses refused to attend. When asked again to attend, Moses arrived carrying a leaky bag of sand over his shoulder. When asked by his brothers why he was carrying the bag of sand, he replied, "My sins run out behind me and I do not see them, but today I am coming to judge the errors of another." Convicted by the truth of his statement, the brothers forgave the offending monk.
Moses later became the leader of a monastic colony in the Western Desert, where he was ordained a priest. Around 405 AD, word came that they were soon to be attacked by Berbers. The monks wanted to take up arms and defend the monastery, but Moses forbade them to do so. He and seven others remained and greeted the attackers with hospitality. All eight men were martyred.
