The Lord prophesies Isaac's birth
The Lord appeared to Abraham by the oaks of Mamre. Three men stood before him, and he ran to meet them and bowed himself to the earth. He brought them food and water to wash their feet and stood by them under the tree.
They asked, "Where is Sarah your wife?" He said, "She is in the tent." The Lord said, "I will surely return to you about this time next year, and Sarah your wife shall have a son." Sarah was listening at the door and laughed, as the way of women had ceased with her. The Lord asked Abraham, "Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ Is anything too hard for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.” But Sarah denied it, saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”
Isaac's birth
The LORD visited Sarah as promised, and Sarah conceived and bore Isaac to Abraham when he was 100 years old. Isaac was circumcised at 8 days old.
Abraham held a great feast when Isaac was weaned. Hagar's son laughed and Sarah demanded he be cast out with Hagar and not be heir with Isaac, and God told Abraham, "Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. And I will make a nation of the son of the slave woman also, because he is your offspring."
While his half-brother Ishmael was taking a wife from Egypt, Isaac sojourned with Abraham in the land of the Philistines many days.
