Genesis 15:7-11

15:7 The Lord said to him, “I am the Lord who brought you out from Ur of the Chaldeans to give you this land to possess.” 15:8 But Abram said, “O sovereign Lord, by what can I know that I am to possess it?”

15:9 The Lord said to him, “Take for me a heifer, a goat, and a ram, each three years old, along with a dove and a young pigeon.” 15:10 So Abram took all these for him and then cut them in two and placed each half opposite the other, but he did not cut the birds in half. 15:11 When birds of prey came down on the carcasses, Abram drove them away.
