15. God said to Abraham, "As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah.

16. I will bless her, and moreover I will give you a son by her. Yes, I will bless her, and she will be a mother of nations. Kings of peoples will come from her."

17. Then Abraham fell on his face, and laughed, and said in his heart, "Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?"

18. Abraham said to God, "Oh that Ishmael might live before you!"

19. God said, "No, but Sarah, your wife, will bear you a son. You shall call his name ISAAC. I will establish my covenant with him for an everlasting covenant for his offspring after him.

1. The LORD appeared to him by the oaks of Mamre, as he sat in the tent door in the heat of the day.

2. He lifted up his eyes and looked, and saw that three men stood opposite him. When he saw them, he ran to meet them from the tent door, and bowed himself to the earth,

3. and said, "My lord, if now I have found favor in your sight, please don't go away from your servant.

4. Now let a little water be fetched, wash your feet, and rest yourselves under the tree.

5. I will get a morsel of bread so you can refresh your heart. After that you may go your way, now that you have come to your servant."They said, "Very well, do as you have said."

6. Abraham hurried into the tent to Sarah, and said, "Quickly prepare three seahs of fine meal, knead it, and make cakes."

7. Abraham ran to the herd, and fetched a tender and good calf, and gave it to the servant. He hurried to dress it.

8. He took butter, milk, and the calf which he had dressed, and set it before them. He stood by them under the tree, and they ate.

9. They asked him, "Where is Sarah, your wife?"He said, "See, in the tent."

10. He said, "I will certainly return to you at about this time next year; and behold, Sarah your wife will have a son."Sarah heard in the tent door, which was behind him.

11. Now Abraham and Sarah were old, well advanced in age. Sarah had passed the age of childbearing.

12. Sarah laughed within herself, saying, "After I have grown old will I have pleasure, my lord being old also?"

13. The LORD said to Abraham, "Why did Sarah laugh, saying, 'Will I really bear a child, yet I am old?'

14. Is anything too hard for The LORD? At the set time I will return to you, when the season comes round, and Sarah will have a son."

15. Then Sarah denied it, saying, "I didn't laugh," for she was afraid.He said, "No, but you did laugh."

1. The LORD visited Sarah as he had said, and the LORD did to Sarah as he had spoken.

2. Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him.

3. Abraham called his son who was born to him, whom Sarah bore to him, ISAAC.

4. Abraham circumcised his son, ISAAC, when he was eight days old, as God had commanded him.

5. Abraham was one hundred years old when his son, ISAAC, was born to him.

6. Sarah said, "God has made me laugh. Everyone who hears will laugh with me."

7. She said, "Who would have said to Abraham, that Sarah would nurse children? For I have borne him a son in his old age."

8. The child grew, and was weaned. Abraham made a great feast on the day that ISAAC was weaned.

I took your father Abraham from beyond the River, and led him throughout all the land of Canaan, and multiplied his offspring, and gave him ISAAC.

The sons of Abraham: ISAAC and Ishmael.

Now we, brothers, as ISAAC was, are children of promise.
