They said to him, “Where is Sarah your wife?” And he said, “She is in the tent.” The LORD said, “I will surely return to you about this time next year, and Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. Now Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. So Sarah laughed to herself, saying, “After I am worn out, and my lord is old, shall I have pleasure?” The LORD said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ Is anything too hard for the LORD? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.” But Sarah denied it, saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”
Then the men set out from there, and they looked down toward Sodom. And Abraham went with them to set them on their way.
Comment: The visitors declare who they are by referring back to the last time God appeared to Abraham, and the previous visit has obviously been fairly recent. Sarah’s impending motherhood was still not evident to her and the one year came into the conversation, but Sarah was listening and thought it all a joke! Sarah, caught out, declined to call the person a liar. Perhaps because she knew who the people were. Abraham, as would have been courteous walked on the way with them as they headed down hill towards Sodom.
Prayer: Help me to take Your threats and promises seriously, O my God.
As I read it!
