3 Abraham called his son who was born to him, whom Sarah bare 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.
9 Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking.
