Genesis 15:10-12 Easy-to-Read Version (ERV)
10 Abram brought all these to God. Abram killed these animals and cut each of them into two pieces. Then he laid each half across from the other half. He did not cut the birds into two pieces. 11 Later, large birds flew down to eat the animals, but Abram chased them away.
12 The sun began to go down and Abram got very sleepy. While he was asleep, a very terrible darkness came over him.
