9 The men said to him, "Where is Sarah your wife?" He said, "In the tent." 10 One of them said, "I'm coming back about this time next year. When I arrive, your wife Sarah will have a son." Sarah was listening at the tent opening, just behind the man. 11 Abraham and Sarah were old by this time, very old. Sarah was far past the age for having babies. 12 Sarah laughed within herself, "An old woman like me? Get pregnant? With this old man of a husband?" 13 God said to Abraham, "Why did Sarah laugh saying, 'Me? Have a baby? An old woman like me?' 14 Is anything too hard for God? I'll be back about this time next year and Sarah will have a baby." 15 Sarah lied. She said, "I didn't laugh," because she was afraid. But he said, "Yes you did; you laughed."

Commentary on Genesis 18:9-15
(Read Genesis 18:9-15)
Where is Sarah thy wife? was asked. Note the answer, In the tent. Just at hand, in her proper place, occupied in her household concerns. There is nothing got by gadding. Those are most likely to receive comfort from God and his promises, who are in their proper place, and in the way of their duty, 17; but He who searches the heart, saw that the one sprung from unbelief, and the other from faith. She denied that she had laughed. One sin commonly brings in another, and it is not likely we shall strictly keep to truth, when we question the Divine truth. But whom the Lord loves he will rebuke, convict, silence, and bring to repentance, and if they sin before him.
