Genesis 18:10-15

10 Then the Lord said, "I will certainly return to you about this time a year from now. At that time your wife Sarah will have a son." Sarah was listening at the entrance of the tent which was behind him.
11 Abraham and Sarah were very old. Since Sarah was past the age when women normally have children,
12 she laughed to herself, "My husband and I are too old to have a baby."
13 Then the Lord said to Abraham, "Why did Sarah laugh? Why did she say, 'I am too old to have a baby'?
14 Is anything too hard for the Lord? No! I will return to you at the right time a year from now, and Sarah will have a son."
15 Sarah was afraid, so she lied and said, "I didn't laugh." But the Lord said, "No. You did laugh."

Genesis 18:10-15 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.

Genesis 18:10-15 In-Context

8 Abraham gave the three men the calf that had been cooked and milk curds and milk. While they ate, he stood under the tree near them.
9 The men asked Abraham, "Where is your wife Sarah?" "There, in the tent," said Abraham.
10 Then the Lord said, "I will certainly return to you about this time a year from now. At that time your wife Sarah will have a son." Sarah was listening at the entrance of the tent which was behind him.
11 Abraham and Sarah were very old. Since Sarah was past the age when women normally have children,
12 she laughed to herself, "My husband and I are too old to have a baby."
13 Then the Lord said to Abraham, "Why did Sarah laugh? Why did she say, 'I am too old to have a baby'?
14 Is anything too hard for the Lord? No! I will return to you at the right time a year from now, and Sarah will have a son."
15 Sarah was afraid, so she lied and said, "I didn't laugh." But the Lord said, "No. You did laugh."
16 Then the men got up to leave and started out toward Sodom. Abraham walked along with them a short time to send them on their way.
17 The Lord said, "Should I tell Abraham what I am going to do now?
