Genesis 18:31 ASV

²⁹  And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for the forty's sake.

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

³¹  And he said, Behold now, I have taken upon me to speak unto the Lord: peradventure there shall be twenty found there. And he said, I will not destroy it for the twenty's sake.

³²  And he said, Oh let not the Lord be angry, and I will speak yet but this once: peradventure ten shall be found there. And he said, I will not destroy it for the ten's sake.

³³  And Jehovah went his way, as soon as he had left off communing with Abraham: and Abraham returned unto his place.
