Tosefta sobre Exodo 23:17

Yochanan ben Dahavei says in the name of Rabbi Yehuda, Neither is a blind man [obligated to appear at the Temple on the Festivals], as it says (Ex. 23:17), "[All of your males] shall be seen," this excludes the blind. Rebbi answered the words of Yochanan ben Dahavei: The Sages decided to support the opinion of (סִיעַ) Rabbi Yehuda [in reliance upon] (1 Sam. 1:22), "Hannah did not ascend, because she said to her husband, 'When the child is weaned, [I will bring him, that he may appear before the Lord]." [Just as a minor is not obligated until he can ascend independently, so too a blind person, who requires support to ascend the Temple, is not obligated to appear (see Chag. 6a:3).]
