27 “You have heard that it was said, ‘Do not commit adultery.’ 28 But I say to you that whoever looks at a woman to desire her has already committed adultery with her in his heart. 29 If your right eye causes you to sin, tear it out and throw it away! It is better to lose one of your members than to have your whole body thrown into hell. 30 If your right hand causes you to sin, cut it off and throw it away! It is better to lose one of your members than to have your whole body go into hell.
And Mar Zutra bar Toviyya says that Rav says; and some say Rav Ḥana bar Bizna says that Rabbi Shimon Ḥasida says; and some say Rabbi Yoḥanan says in the name of Rabbi Shimon ben Yoḥai: It is more comfortable for a person to cast himself into a fiery furnace, than to humiliate another in public to avoid being cast into the furnace. From where do we derive this? From Tamar, daughter-in-law of Judah. When she was taken out to be burned, she did not reveal that she was pregnant with Judah’s child. Rather, she left the decision to him, to avoid humiliating him in public, as it is written: “And Judah said: Bring her forth, and let her be burnt. When she was brought forth, she sent to her father-in-law, saying: I am pregnant by the man to whom these belong. And she said: Examine these, whose are these, the signet, and the cords, and the staff?” (Genesis 38:24–25).
