Genesis 15:12

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.”

He brought him all these, and divided them in the middle, and laid each half opposite the other; but he didn’t divide the birds.

The birds of prey came down on the carcasses, and Abram drove them away.

He said to Abram, “Know for sure that your offspring will live as foreigners in a land that is not theirs, and will serve them. They will afflict them four hundred years.

I will also judge that nation, whom they will serve. Afterward they will come out with great wealth;

but you will go to your fathers in peace. You will be buried at a good old age.
