The son of Rabbi Yohanan ben Zakkai had fallen dangerously ill. His father, the greatest sage of his generation, prayed — and nothing happened. Yohanan then sent word to a strange, poor mystic who lived alone in the hills: Rabbi Hanina ben Dosa.
Hanina was not a scholar of the first rank. He had no academy, no disciples, no wealth. But he had a reputation for prayer the way other rabbis had reputations for legal brilliance. When Hanina prayed, things happened.
The messenger arrived at Hanina's simple house. Hanina withdrew to an upper room. He prayed — the tradition says he rested his head between his knees in the ancient posture of concentrated plea. And somewhere in Yohanan's household, the son's fever broke.
When Hanina came down, he said simply, "The child will live."
The messenger rode back. Yohanan's wife asked her husband why Hanina's prayer could do what her husband's could not. Yohanan answered, "I am a prince in God's court. He is a slave. The slave has freer access to the Master than the prince does."
Gaster's Exempla (no. 166, 1924) preserves this story as a one-sentence pointer to a longer tradition in Berakhot 34b. The sages kept it close because it pushed against one of their own assumptions. Scholarship does not corner the market on prayer. Sometimes the poor man in the hills, who knows nothing but how to kneel, is heard first.
