Genesis 15:10-12

New Century Version

¹⁰ Abram brought them all to God. Then Abram killed the animals and cut each of them into two pieces, laying each half opposite the other half. But he did not cut the birds in half. ¹¹ Later, large birds flew down to eat the animals, but Abram chased them away.

¹² As the sun was going down, Abram fell into a deep sleep. While he was asleep, a very terrible darkness came.
