Genesis 18:28 Meaning and Commentary

Genesis 18:28

Peradventure there should lack five of the fifty righteous,
&c.] Or there should be but forty five; for Abraham perceived, by the Lord's answer, that there were not fifty righteous persons in the place: wilt thou destroy all the city for [lack of] five?

that is, forty five righteous persons.
