Genesis 17:15-18:15

15God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah.

16I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.” 17Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?”

18And Abraham said to God, “If only Ishmael might live under your blessing!” 19Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac. Isaac means he laughs. I will establish my covenant with him as an everlasting covenant for his descendants after him. 20And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. 21But my covenant I will establish with Isaac, whom Sarah will bear to you by this time next year.”

22When he had finished speaking with Abraham, God went up from him. 23On that very day Abraham took his son Ishmael and all those born in his household or bought with his money, every male in his household, and circumcised them, as God told him. 24Abraham was ninety-nine years old when he was circumcised, 25and his son Ishmael was thirteen; 26Abraham and his son Ishmael were both circumcised on that very day. 27And every male in Abraham’s household, including those born in his household or bought from a foreigner, was circumcised with him.

The Three Visitors 1The LORD appeared to Abraham near the great trees of Mamre while he was sitting at the entrance to his tent in the heat of the day.

2Abraham looked up and saw three men standing nearby. When he saw them, he hurried from the entrance of his tent to meet them and bowed low to the ground. 3He said, “If I have found favor in your eyes, my lord, Or eyes, Lord do not pass your servant by. 4Let a little water be brought, and then you may all wash your feet and rest under this tree.

5Let me get you something to eat, so you can be refreshed and then go on your way—now that you have come to your servant.” “Very well,” they answered, “do as you say.”

6So Abraham hurried into the tent to Sarah. “Quick,” he said, “get three seahs That is, probably about 36 pounds or about 16 kilograms of the finest flour and knead it and bake some bread.” 7Then he ran to the herd and selected a choice, tender calf and gave it to a servant, who hurried to prepare it.

8He then brought some curds and milk and the calf that had been prepared, and set these before them. While they ate, he stood near them under a tree.

9“Where is your wife Sarah?” they asked him. “There, in the tent,” he said.

10Then one of them said, “I will surely return to you about this time next year, and Sarah your wife will have a son.” Now Sarah was listening at the entrance to the tent, which was behind him. 11Abraham and Sarah were already very old, and Sarah was past the age of childbearing.

12So Sarah laughed to herself as she thought, “After I am worn out and my lord is old, will I now have this pleasure?” 13Then the LORD said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child, now that I am old?’

14Is anything too hard for the LORD ? I will return to you at the appointed time next year, and Sarah will have a son.”

15Sarah was afraid, so she lied and said, “I did not laugh.” But he said, “Yes, you did laugh.”
