Eleazar explained that Tamar had covered her face in her father-in-law's house (and thus Judah had never seen her face and did not recognize her), for Rabbi Samuel bar Nahmani said in the name of Rabbi Jonathan that every daughter-in-law who is modest in her father-in-law's house merits that kings and prophets should issue from her. In support of that proposition, the Gemara noted that kings descended from Tamar through David. And prophets descended from Tamar, as says, "The vision of Isaiah the son of Amoz," and Rabbi Levi taught that there is a tradition that Amoz was the brother of Amaziah the King of Judah, and thus a descendant of David and thus of Tamar.

For even to save herself from being burned, Tamar in did not implicate Judah publicly by name. Similarly, the Gemara derived from a lesson about how to give to the poor. The Gemara told a story. A poor man lived in Mar Ukba's neighborhood, and every day Mar Ukba would put four zuz into the poor man's door socket. One day, the poor man thought that he would try to find out who did him this kindness. That day Mar Ukba came home from the house of study with his wife. When the poor man saw them moving the door to make their donation, the poor man went to greet them, but they fled and ran into a furnace from which the fire had just been swept. They
