Genesis 18:13 Meaning and Commentary

Genesis 18:13

And the Lord said unto Abraham
This discovers who the person was that had been conversing with Abraham, that he was a divine Person, as appears by his name "Jehovah", as well as by his knowledge of Sarah's behaviour; he did not turn himself to her, that it might be more manifest that it was not upon the sight of her he judged she laughed, but from his own omniscience; and he chose rather to speak to her husband than to her, appearing as a stranger, and that he might reprove her: wherefore did Sarah laugh, saying, shall I of a surety bear a child,
which am old?
suggesting there was no reason for it, and signifying his displeasure and indignation at it.

Genesis 18:13 In-Context

11 Abraham and Sarah were old and getting on in years. Sarah had passed the age of childbearing.

12 So she laughed to herself: "After I have become shriveled up and my lord is old, will I have delight?"

13 But the Lord asked Abraham, "Why did Sarah laugh, saying, 'Can I really have a baby when I'm old?'

14 Is anything impossible for the Lord? At the appointed time I will come back to you, and in about a year she will have a son."

15 Sarah denied it. "I did not laugh," she said, because she was afraid. But He replied, "No, you did laugh."
