The Birth and Naming of Isaac

Genesis 21:1-8

ADONAI remembered Sarah as he had said, and ADONAI did for Sarah what he had promised.

Sarah conceived and bore Avraham a son in his old age, at the very time God had said to him.

Avraham called his son, born to him, whom Sarah bore to him, Yitz'chak.

Avraham circumcised his son Yitz'chak when he was eight days old, as God had ordered him to do.

Avraham was one hundred years old when his son Yitz'chak [laughter] was born to him.

Sarah said, "God has given me good reason to laugh; now everyone who hears about it will laugh with me."

And she said, "Who would have said to Avraham that Sarah would nurse children? Nevertheless, I have borne him a son in his old age!"

The child grew and was weaned, and Avraham gave a great banquet on the day that Yitz'chak was weaned.
