Genesis 15:9 BBE

⁷  And he said to him, I am the Lord, who took you from Ur of the Chaldees, to give you this land for your heritage.

⁸  And he said, O Lord God, how may I be certain that it will be mine?

⁹  And he said, Take a young cow of three years old, and a she-goat of three years old, and a sheep of three years old, and a dove and a young pigeon.

¹⁰  All these he took, cutting them in two and putting one half opposite the other, but not cutting the birds in two.

¹¹  And evil birds came down on the bodies, but Abram sent them away.
