Genesis 20:17-21:3

BBE(i) 17 Then Abraham made prayer to God, and God made Abimelech well again, and his wife and his women-servants, so that they had children. 18 For the Lord had kept all the women of the house of Abimelech from having children, because of Sarah, Abraham's wife. 21 1 And the Lord came to Sarah as he had said and did to her as he had undertaken. 2 And Sarah became with child, and gave Abraham a son when he was old, at the time named by God. 3 And Abraham gave to his son, to whom Sarah had given birth, the name Isaac.
