Genesis 15:6

3 Abram said, "Behold, to me you have given no seed: and, behold, one born in my house is my heir."

4 Behold, the word of Yahweh came to him, saying, "This man will not be your heir, but he who will come forth out of your own body will be your heir."

5 Yahweh brought him outside, and said, "Look now toward the sky, and count the stars, if you be able to count them." He said to Abram, "So shall your seed be."

6 He believed in Yahweh; and he reckoned it to him for righteousness.

7 He said to him, "I am Yahweh who brought you out of Ur of the Chaldees, to give you this land to inherit it."

8 He said, "Lord Yahweh, whereby will I know that I will inherit it?"

9 He said to him, "Take me a heifer three years old, a female goat three years old, a ram three years old, a turtle-dove, and a young pigeon."
