Genesis 15:11-13 New Living Translation (NLT)

11. Some vultures swooped down to eat the carcasses, but Abram chased them away.

12. As the sun was going down, Abram fell into a deep sleep, and a terrifying darkness came down over him.

13. Then the lord said to Abram, “You can be sure that your descendants will be strangers in a foreign land, where they will be oppressed as slaves for 400 years.
