The Sign of the Covenant (Genesis 16)

                   and said to him, I am Almighty God; walk before Me and be blameless.  "And I will make My covenant between Me and you, and will multiply you exceedingly."  Then Abram fell on his face, and God talked with him, saying:  As for Me, behold, My covenant is with you, and you shall be a father of many nations.  No longer shall your name be called Abram, but your name shall be Abaham: for I have made you a father of many nations.
