תלמוד על סנהדרין 2:4

Ben Yehoṣadaq was priding himself for his vaulting. ⁷⁸Babli 53a. The corrector’s change [in brackets] follows the Babli and should be deleted. In the Babli the torches are lit. They said about Rabban Simeon ben Gamliel that he was dancing with eight golden torches and neither of them touched (the ground) [any other.] When he was bowing down to his shinbone he thrust his thumb into the ground, bowed down to his shinbone, and immediately stood up. ⁷⁹Parallels are in Berakhot1:8 (Note 249), Gen. rabba39(18). The text in Berakhot editio princeps is the corrector’s, quite different from the scribe’s which is consistent with the text here. What is bowing down to one’s shinbone and what is kneeling? The great Rebbi Ḥiyya showed bowing down to his shinbone before Rebbi, [became lame] and was healed. Levi ben Sisi showed kneeling before Rebbi, became lame and was not healed.
