Genesis 15:9-21 KJV

[9] And he said unto him, Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon.

[10] And he took unto him all these, and divided them in the midst, and laid each piece one against another: but the birds divided he not.

[11] And when the fowls came down upon the carcases, Abram drove them away. [12] And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him. [13] And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; [14] And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance. [15] And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. [16] But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full. [17] And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces. [18] In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: [19] The Kenites, and the Kenizzites, and the Kadmonites, [20] And the Hittites, and the Perizzites, and the Rephaims, [21] And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.
