Genesis 18:27, 30-32

And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, who am but dust and ashes

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. 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. 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.
