Genesis 18:28 WBT

²⁶  And the LORD said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.

²⁷  And Abraham answered and said, Behold now, I, who [am] dust and ashes, have taken upon me to speak to the Lord.

²⁸  Peradventure there will lack five of the fifty righteous: 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 to him yet again, and said, Peradventure there will be forty found there. And he said, I will not do [it] for forty's sake.

³⁰  And he said, Oh, let not the Lord be angry, and I will speak: Peradventure there will thirty be found there. And he said, I will not do [it], if I find thirty there.
