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 Now Abraham and Sarah [were] old, {advanced in age}; {the way of women} had ceased to be for Sarah.

12 So Sarah laughed to herself saying, "After I am worn out and my husband is old, shall [this] pleasure be to me?"

13 Then Yahweh said to Abraham, "What [is] this [that] Sarah laughed, saying, 'Is it indeed true [that] I will bear a child, now [that] I have grown old?'

14 Is anything too difficult for Yahweh? At the appointed time I will return to you {in the spring} and Sarah [shall have] a son."

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