R. Chanina ben Dosa

Rabbi Chanina ben Dosa was a first-century Tanna who lived in Araba in the Lower Galilee during the Second Temple period. Though he lived in relative poverty, he was renowned throughout Jewish tradition as a man of extraordinary piety and miraculous powers. The Talmud recounts numerous incidents of his prayers being answered and of heavenly voices (bat kol) affirming his righteousness. He was known for his ascetic lifestyle, his deep faith, and his ability to heal the sick through prayer. His students included Rabbi Yochanan ben Zakkai, and he was widely respected as a model of trust in Divine providence. Though he left no systematic legal rulings, his example of piety and devotion profoundly influenced Jewish ethical thought.
