Genesis 15:1-12, 17-18
15:1 After these things the word of the LORD came to Abram in a vision, "Do not be afraid, Abram, I am your shield; your reward shall be very great."

15:2 But Abram said, "O Lord GOD, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?"

15:3 And Abram said, "You have given me no offspring, and so a slave born in my house is to be my heir."

15:4 But the word of the LORD came to him, "This man shall not be your heir; no one but your very own issue shall be your heir."

15:5 He brought him outside and said, "Look toward heaven and count the stars, if you are able to count them." Then he said to him, "So shall your descendants be."

15:6 And he believed the LORD; and the LORD reckoned it to him as righteousness.

15:7 Then he said to him, "I am the LORD who brought you from Ur of the Chaldeans, to give you this land to possess."

15:8 But he said, "O Lord GOD, how am I to know that I shall possess it?"

15:9 He said to him, "Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon."

15:10 He brought him all these and cut them in two, laying each half over against the other; but he did not cut the birds in two.

15:11 And when birds of prey came down on the carcasses, Abram drove them away.

15:12 As the sun was going down, a deep sleep fell upon Abram, and a deep and terrifying darkness descended upon him.

15:17 When the sun had gone down and it was dark, a smoking fire pot and a flaming torch passed between these pieces.

15:18 On that day the LORD made a covenant with Abram, saying, "To your descendants I give this land, from the river of Egypt to the great river, the river Euphrates...."
