New Defender's Study Bible Notes
18:23 destroy the righteous. This is the most remarkable passage of intercessory prayer in the Bible, also indicating how vitally important is the presence of even a tiny godly minority in an ungodly community. This model intercessory prayer continually appeals both to God’s righteous character and His lovingkindness, as the basis for making the request. Abraham thought he knew of ten righteous people in Sodom (Lot and his family of two unmarried sons, two unmarried daughters, two married daughters and their husbands), not realizing that most of Lot’s family had been caught up in the city’s wickedness, and so stopped his intercession at ten.
18:25 Judge of all the earth. God is still the judge of all the earth, not only of the chosen nation, and Abraham recognized this.
