Genesis 18:23–32

²³And drawing nigh, he said: Wilt thou destroy the just with the wicked?

²⁴If there be fifty just men in the city, shall they perish withal? and wilt thou not spare that place for the sake of the fifty just, if they be therein?

²⁵Far be it from thee to do this thing, and to slay the just with the wicked, and for the just to be in like case as the wicked; this is not beseeming thee: thou who judgest all the earth, wilt not make this judgment.

²⁶And the Lord said to him: If I find in Sodom fifty just within the city, I will spare the whole place for their sake.

²⁷And Abraham answered, and said: Seeing I have once begun, I will speak to my Lord, whereas I am dust and ashes.

²⁸What if there be five less than fifty just persons? wilt thou for five and forty destroy the whole city: And he said: I will not destroy it, if I find five and forty.

²⁹And again he said to him: But if forty be found there, what wilt thou do? He said: I will not destroy it for the sake of forty.

³⁰Lord, saith he, be not angry, I beseech thee, if I speak: What if thirty shall be found there? He answered: I will not do it, if I find thirty there.

³¹Seeing, saith he, I have once begun, I will speak to my Lord: What if twenty be found there? He said: I will not destroy it for the sake of twenty.

³²I beseech thee, saith he, be not angry, Lord, if I speak yet once more: What if ten shall be found there? And he said: I will not destroy it for the sake of ten.
