Genesis 17:5-7

LXX2012(i) 5 And your name shall no more be called Abram, but your name shall be Abraam, for I have made you a father of many nations. 6 And I will increase you very exceedingly, and I will make nations of you, and kings shall come out of you. 7 And I will establish my covenant between you and your seed after you, to their generations, for an everlasting covenant, to be your God, and [the God] of your seed after you.
