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.
