The LORD visited Sarah as he had said, and the LORD did to Sarah as he had spoken.
Sarah conceived, and bore Avraham a son in his old age, at the set time of which God had spoken to him.
Avraham called his son who was born to him, whom Sarah bare to him, Yitzchak.
Avraham circumcised his son, Yitzchak, when he was eight days old, as God had commanded him.
Avraham was one hundred years old when his son, Yitzchak, was born to him.
Sarah said, "God has made me laugh. Everyone who hears will laugh with me."
