(Translated according to Ehrfurt manuscript). "With the understanding that I am a sage"—he did not say like either Shimon ben Azzai or Shimon ben Zoma, but all the people of his town pay him respect. "With this silver dinar", but it turned out to be of gold—she is not betrothed. What should he do? Take it from her, return and give it to her, and say to her: "Behold you are betrothed to me."
