Genesis 18:11-15

11 Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women.
12 So Sarah laughed to herself, saying, "After I have grown old, and my husband is old, shall I have pleasure?"
13 The Lord said to Abraham, "Why did Sarah laugh, and say, "Shall I indeed bear a child, now that I am old?'
14 Is anything too wonderful for the Lord? At the set time I will return to you, in due season, and Sarah shall have a son."
15 But Sarah denied, saying, "I did not laugh"; for she was afraid. He said, "Oh yes, you did laugh."

Genesis 18:11-15 Meaning and Commentary

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, Ge 18:1-8; 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, Ge 18:9-15; upon their departure the Lord thought fit, for reasons given, to make known to Abraham his intention to destroy Sodom and Gomorrah, Ge 18:16-22; when Abraham intercedes for the preservation of those cities in a most importunate and affectionate manner, Ge 18:23-33.
