Genesis 15:9-11

Revised Standard Version

⁹ He said to him, “Bring me a heifer three years old, a she-goat three years old, a ram three years old, a turtledove, and a young pigeon.” ¹⁰ And he brought him all these, cut them in two, and laid each half over against the other; but he did not cut the birds in two. ¹¹ And when birds of prey came down upon the carcasses, Abram drove them away.
