Genesis 15:9-11

New Revised Standard Version Catholic Edition

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