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 And Sarah is hearkening at the opening of the tent, which is behind him;
12 and Abraham and Sarah [are] aged, entering into days -- the way of women hath ceased to be to Sarah;
13 and Sarah laugheth in her heart, saying, `After I have waxed old I have had pleasure! -- my lord also [is] old!'
14 And Jehovah saith unto Abraham, `Why [is] this? Sarah hath laughed, saying, Is it true really -- I bear -- and I am aged? Is any thing too wonderful for Jehovah? at the appointed time I return unto thee, about the time of life, and Sarah hath a son.'
15 And Sarah denieth, saying, `I did not laugh;' for she hath been afraid; and He saith, `Nay, but thou didst laugh.'
