Genesis Chapter 15 Verse 13And 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 Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.

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

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.

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.
