Genesis 20:17-21:3

Leeser(i) 17 And Abraham prayed unto God; and God healed Abimelech, and his wife, and his maid-servants, so that they could bear children. 18 For the Lord had fast closed up every womb of the house of Abimelech, because of Sarah, Abraham’s wife. 21 1 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken. 2 And Sarah conceived, and bore unto Abraham a son in his old age, at the appointed time of which God had spoken to him. 3 And Abraham called the name of his son that was born unto him, whom Sarah bore to him, Isaac.
