Palestinian amora. His period is unknown. Two haggadot of his are extant. The king Melchizedek, who went to meet Abraham, was called Salem, says Yiẓḥaḳ, because he was perfect; that is, he had early submitted to circumcision (Gen. R. 43:7). With reference to Jacob's promise, the amora interprets the words "Which my lips have uttered, and my mouth hath spoken when I was in trouble" (Psalms 66:14) by saying that one makes a vow when in need, in order to keep the commandments of the Torah (Gen. R. 70:1; Midrash Shemuel ).
