Genesis 15:8-10

New Catholic Bible

⁸ He answered, “O Lord God, how will I know that I am to possess it?”

⁹ He said, “Take a three-year-old heifer, a three-year-old she-goat, a three-year-old ram, a turtledove, and a young pigeon.”

¹⁰ He took all these animals and split them in two and placed each half opposite the other (except for the birds).
