did so because, as Mar Zutra bar Tobiah said in the name of Rav (or others say Rav Huna bar Bizna said in the name of Rabbi Simeon the Pious, and still others say Rabbi Johanan said in the name of Rabbi Simeon ben Yohai), it is better for a person to go into a fiery furnace than to shame a neighbor publicly. One can derive this from , where Tamar, who was subject to being burned for the adultery with which Judah had charged her, rather than publicly shame Judah with the facts of his complicity, sent Judah's possessions to him with the message, "By the man whose these are am I with child."

Genesis chapter 39 Reading the words of , “And Potiphar, an officer (, seris) of Pharaoh's, bought him,” Rav taught that Potiphar bought Joseph for himself (to make Joseph his lover), but the archangel Gabriel castrated Potiphar (as the Hebrew word for “officer,” , seris, also means “eunuch”) and then mutilated Potiphar, for originally records his
