Genesis 15:10-12 Expanded Bible (EXB)
10 Abram brought them all to God. Then Abram ·killed the animals and cut each of them into two pieces [L split them down the middle], laying each half opposite the other half. But he did not cut the birds in half. 11 Later, ·large birds [or birds of prey] flew down to eat the ·animals [L carcasses], but Abram chased them away [C perhaps representing later enemies of Israel].
12 As the sun was ·going down [setting], Abram fell into a deep sleep. While he was asleep, a very ·terrible [or frightening] darkness came.
