Genesis 15:9-17

So God said to him, “Bring Me a three-year-old heifer, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon.” So Abram brought all these to Him and cut them down the middle, and laid each half opposite the other; but he did not cut the birds. The birds of prey swooped down on the carcasses, but Abram drove them away. When the sun was setting, a deep sleep overcame Abram; and a horror (terror, shuddering fear, nightmare) of great darkness overcame him. God said to Abram, “Know for sure that your descendants will be strangers [living temporarily] in a land (Egypt) that is not theirs, where they will be enslaved and oppressed for four hundred years. [Ex 12:40] But on that nation whom your descendants will serve I will bring judgment, and afterward they will come out [of that land] with great possessions. [Ex 12:35, 36; Acts 7:6, 7] As for you, you shall [die and] go to your fathers in peace; you shall be buried at a good old age. Then in the fourth generation your descendants shall return here [to Canaan, the land of promise], for the wickedness and guilt of the Amorites is not yet complete (finished).” [Josh 24:15] When the sun had gone down and a [deep] darkness had come, there appeared a smoking brazier and a flaming torch which passed between the [divided] pieces [of the animals]. [Jer 34:18, 19]
