Genesis 18:3-13

3 and said, "My lord, if I have found favor in your sight, please don't leave your servant.
4 Please let me send for some water, so that you can wash your feet; then rest under the tree,
5 and I will bring a piece of bread. Now that you have come to your servant, refresh yourselves before going on.""Very well," they replied, "do what you have said."
6 Avraham hurried into the tent to Sarah and said, "Quickly, three measures of the best flour! Knead it and make cakes."
7 Avraham ran to the herd, took a good, tender calf and gave it to the servant, who hurried to prepare it.
8 Then he took curds, milk and the calf which he had prepared, and set it all before the men; and he stood by them under the tree as they ate.
9 They said to him, "Where is Sarah your wife?" He said, "There, in the tent."
10 He said, "I will certainly return to you around this time next year, and Sarah your wife will have a son."Sarah heard him from the entrance of the tent, behind him.
11 Avraham and Sarah were old, advanced in years; Sarah was past the age of childbearing.
12 So Sarah laughed to herself, thinking, "I am old, and so is my lord; am I to have pleasure again?"
13 ADONAI said to Avraham, "Why did Sarah laugh and ask, 'Am I really going to bear a child when I am so old?'
