Romans 4
17 Ref (As it is said in the holy Writings, I have made you a father of a number of nations) before him in whom he had faith, that is, God, who gives life to the dead, and to whom the things which are not are as if they were.
18 Ref Who without reason for hope, in faith went on hoping, so that he became the father of a number of nations, as it had been said, So will your seed be.
