Genesis 15:10-12 New Life Version (NLV)
10 Then Abram brought all these to Him, and cut them in two. And he laid each half beside the other. But he did not cut the birds. 11 When the meat-eating birds came down upon the dead animals, Abram made them go away.
12 When the sun was going down, Abram went into a sleep as if he were dead. And much fear and darkness came upon him.
