INTRODUCTION TO GENESIS 18 Another appearance of God to Abraham is here recorded; three persons are seen by him in an human form, whom he kindly invites to stop with him, and generously entertains them, Gen 18:1; they inquire concerning Sarah his wife, and one of them renews the promise of her bearing a son to him, which occasions laughter in her, for which she is reproved, Gen 18:9; upon their departure the Lord thought fit, for reasons given, to make known to Abraham his intention to destroy Sodom and Gomorrah, Gen 18:16; when Abraham intercedes for the preservation of those cities in a most importunate and affectionate manner, Gen 18:23.
