3 Abraham called the name of his son who was born to him, whom Sarah bore to him, Isaac.
4 Then Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.
5 Now Abraham was one hundred years old when his son Isaac was born to him.
6 Sarah said, "God has made laughter for me; everyone who hears will laugh with me."
7 And she said, "Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age."
8 The child grew and was weaned, and Abraham made a great feast on the day that Isaac was weaned.
9 Now Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking.
