Saint David of Hermopolis (6th century) was once the leader of a band of robbers living in Egypt. After reaching an old age, he reflected deeply on his life, repented sincerely, and trembled at the memory of his crimes. Determined to change completely, he went to a monastery and persistently begged to be accepted into the brotherhood. Seeing his deep devotion and steadfastness, the abbot finally received him into the monastery. In time, David astonished the brethren through the strictness of his asceticism and his unwavering obedience to the monastic rule.
Through great struggles and labors, the saint became worthy of receiving the Grace of God. Archangel Gabriel appeared before him and brought him the joyful message that his sins had been forgiven. Yet David, filled with humility, could scarcely believe that the Lord had shown mercy so quickly to such a sinful man as himself. Because of his unbelief, he was punished by losing the power of speech, which was restored to him only when he prayed, read his monastic rule, or participated in the divine services.
Toward the end of his life, God granted him the gift of performing miracles. He healed the sick and cast out evil spirits. Having reached an old age, the venerable saint reposed peacefully in the Lord.
