Genesis 15:11-13 New American Bible, Revised Edition (NABRE)

11. Birds of prey swooped down on the carcasses, but Abram scared them away.

12. As the sun was about to set, a deep sleep fell upon Abram, and a great, dark dread descended upon him.

13. Then the Lord said to Abram: Know for certain that your descendants will reside as aliens in a land not their own, where they shall be enslaved and oppressed for four hundred years.
