Genesis 17:2-5

JPS_ASV_Byz(i) 2 And I will make My covenant between Me and thee, and will multiply thee exceedingly.' 3 And Abram fell on his face; and God talked with him, saying: 4 'As for Me, behold, My covenant is with thee, and thou shalt be the father of a multitude of nations. 5 Neither shall thy name any more be called Abram, but thy name shall be Abraham; for the father of a multitude of nations have I made thee.
