Bereshis 18:27-29

Orthodox Jewish Bible

²⁷ And Avraham answered and said, Hinei now, I, which am but aphar and ashes, have taken upon me to speak unto Hashem;

²⁸ Suppose there shall lack five of the fifty tzaddikim; wilt Thou destroy all the city for lack of five? And He said, If I find there forty and five, I will not destroy it.

²⁹ And he spoke unto Him yet again, and said, Suppose there shall be forty found there. And He said, I will not do it for forty’s sake.
