In context
4Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5Abraham was a hundred years old when his son Isaac was born to him. 6Sarah said, “God has made laughter for me. Everyone who hears will laugh with me.” 7She said, “Who would have told Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.” 8The child grew and was weaned, and on the day Isaac was weaned Abraham held a great feast.
