The Lord had said to Abram, “Go from your country, your people and your father’s household to the land I will show you.
“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.
I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth
will be blessed through you.”
So Abram went, as the Lord had told him; and Lot went with him. Abram was seventy-five years old when he set out from Harran. He took his wife Sarai, his nephew Lot, all the possessions they had accumulated and the people they had acquired in Harran, and they set out for the land of Canaan, and they arrived there.
Abram traveled through the land as far as the site of the great tree of Moreh at Shechem. At that time the Canaanites were in the land. The Lord appeared to Abram and said, “To your offspring I will give this land.” So he built an altar there to the Lord, who had appeared to him.
(15:1-6)
After this, the word of the Lord came to Abram in a vision: “Do not be afraid, Abram. I am your shield, your very great reward.”
But Abram said, “Sovereign Lord, what can you give me since I remain childless and the one who will inherit my estate is Eliezer of Damascus?” And Abram said, “You have given me no children; so a servant in my household will be my heir.”
Then the word of the Lord came to him: “This man will not be your heir, but a son who is your own flesh and blood will be your heir.” He took him outside and said, “Look up at the sky and count the stars—if indeed you can count them.” Then he said to him, “So shall your offspring be.”
Abram believed the Lord, and he credited it to him as righteousness.
17:1-7
When Abram was ninety-nine years old, the Lord appeared to him and said, “I am God Almighty; walk before me faithfully and be blameless. Then I will make my covenant between me and you and will greatly increase your numbers.”
Abram fell facedown, and God said to him, “As for me, this is my covenant with you: You will be the father of many nations. No longer will you be called Abram; your name will be Abraham, for I have made you a father of many nations. 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.
