Abrahamic Covenant
  Genesis 12-17
Genesis 12:2-3 -  "I will make you into a great nation and I will bless you; I will make your name great, and you will be a blessing. 3 I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you."
Genesis 13:16 - I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted.
Genesis 15:5 - He took him outside and said, "Look up at the heavens and count the stars-- if indeed you can count them." Then he said to him, "So shall your offspring be."
Genesis 15:18  - On that day the LORD made a covenant with Abram and said, "To your descendants I give this land. .
Genesis 17:6-11 - I will make you very fruitful; I will make nations of you, and kings will come from you. I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you. The whole land of Canaan, where you are now an alien, I will give as an everlasting possession to you and your descendants after you; and I will be their God." Then God said to Abraham, "As for you, you must keep my covenant, you and your descendants after you for the generations to come. This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised. You are to undergo circumcision, and it will be the sign of the covenant between me and you. For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner-- those who are not your offspring. Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be an everlasting covenant. Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant."
