Genesis 15:7-11

7Then the Lord said to him, “I am the Lord, who brought you out of Ur of the Chaldeans to give you this land so that you will take possession of it.”

8Abram asked, “Almighty Lord, how can I be certain that I will take possession of it?”

9He answered Abram, “Bring me a three-year-old heifer, a three-year-old female goat, a three-year-old ram, a mourning dove, and a pigeon.”

10So Abram brought all these animals to him. He cut each of them in half and laid each half opposite the other. However, he did not cut the birds in half.

11When birds of prey came down upon the carcasses, Abram drove them away.
