Then he said, 'Oh may the Lord not be angry, and I shall speak only this once; suppose ten are found there?' And He said, 'I will not destroy it on account of the ten.'
(New American Standard Bible)
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 ten's sake.
(King James Version)
