Genesis 18:31-33 American Standard Version (ASV)
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.
