Genesis 18:29-31

Darby Translation

²⁹ And he continued yet to speak with him, and said, Perhaps there may 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 that I speak! Perhaps there may be thirty found there. And he said, I will not do it if I find thirty there.

³¹ And he said, Behold now, I have ventured to speak with the Lord. Perhaps there may be twenty found there. And he said, I will not destroy [it] for the twenty's sake.
