1 Then the LORD took note of Sarah as He had said, and the LORD did for Sarah as He had promised. 2 So Sarah conceived and bore a son to Abraham in his old age, at the appointed time of which God had spoken to him. 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."
