Genesis Chapter 15 Verse 17And 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.

And he said unto him, I [am] the LORD that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.

And he said, Lord GOD, whereby shall I know that I shall inherit it?

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.

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.

And when the fowls came down upon the carcases, Abram drove them away.

And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him.

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;

And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance.

And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age.

But in the fourth generation they shall come hither again: for the iniquity of the Amorites [is] not yet full.

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:

The Kenites, and the Kenizzites, and the Kadmonites,

And the Hittites, and the Perizzites, and the Rephaims,

And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.

Now Sarai Abram's wife bare him no children: and she had an handmaid, an Egyptian, whose name [was] Hagar.

And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.

And Sarai Abram's wife took Hagar her maid the Egyptian, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife.

And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes.

And Sarai said unto Abram, My wrong [be] upon thee: I have given my maid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: the LORD judge between me and thee.

But Abram said unto Sarai, Behold, thy maid [is] in thy hand; do to her as it pleaseth thee. And when Sarai dealt hardly with her, she fled from her face.
