9 "Where is Sarah, your wife?" the visitors asked. "She's inside the tent," Abraham replied. 10 Then one of them said, "I will return to you about this time next year, and your wife, Sarah, will have a son!" Sarah was listening to this conversation from the tent. 11 Abraham and Sarah were both very old by this time, and Sarah was long past the age of having children. 12 So she laughed silently to herself and said, "How could a worn-out woman like me enjoy such pleasure, especially when my master-my husband-is also so old?" 13 Then the Lord said to Abraham, "Why did Sarah laugh? Why did she say, 'Can an old woman like me have a baby?' 14 Is anything too hard for the Lord ? I will return about this time next year, and Sarah will have a son." 15 Sarah was afraid, so she denied it, saying, "I didn't laugh." But the Lord said, "No, you did laugh."
16 Then the men got up from their meal and looked out toward Sodom. As they left, Abraham went with them to send them on their way. 17 "Should I hide my plan from Abraham?" the Lord asked. 18 "For Abraham will certainly become a great and mighty nation, and all the nations of the earth will be blessed through him. 19 I have singled him out so that he will direct his sons and their families to keep the way of the Lord by doing what is right and just. Then I will do for Abraham all that I have promised."

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.
Commentary on Genesis 18:16-22
(Read Genesis 18:16-22)
The two who are supposed to have been created angels went toward Sodom. The one who is called Jehovah throughout the chapter, continued with Abraham, and would not hide from him the thing he intended to do. Though God long forbears with sinners, from which they fancy that the Lord does not see, and does not regard; yet when the day of his wrath comes, he will look toward them. The Lord will give Abraham an opportunity to intercede with him, and shows him the reason of his conduct. Consider, as a very bright part of Abraham's character and example, that he not only prayed with his family, but he was very careful to teach and rule them well. Those who expect family blessings must make conscience of family duty. Abraham did not fill their heads with matters of doubtful dispute; but he taught them to be serious and devout in the worship of God, and to be honest in their dealings with all men. Of how few may such a character be given in our days! How little care is taken by masters of families to ground those under them in the principles of religion! Do we watch from sabbath to sabbath whether they go forward or backward?
