Genesis 18:29

And he continued to speak to him still, and said, But if there should be found there forty? And he said, I will not destroy it for the forty's sake.

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 forty’s sake.

He spoke to him yet again, and said, “What if there are forty found there?” He said, “I will not do it for the forty’s sake.”
