God promises Abraham children and again promises the land of Canaan to those children forever.

GENESIS 15:1  After these things the word of the LORD came unto Abram in a vision,  saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.

GENESIS 15:2  And Abram said, LORD God, what wilt thou give me, seeing I go  childless, and the steward of my house is this Eliezer of Damascus?

GENESIS 15:3  And Abram said, Behold, to me thou hast given no seed: and, lo, one  born in my house is mine heir.

GENESIS 15:4  And, behold, the word of the LORD came unto him, saying, This shall  not be thine heir; but he that shall come forth out of thine own bowels shall  be thine heir.

GENESIS 15:5  And he brought him forth abroad, and said, Look now toward  heaven, and tell the stars, if thou be able to number them: and he said unto  him, So shall thy seed be.

GENESIS 15:6  And he believed in the LORD; and he counted it to him for  righteousness.

GENESIS 15:7  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.

GENESIS 15:8  And he said, LORD God, whereby shall I know that I shall inherit it?

GENESIS 15:9  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.

GENESIS 15:10  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.

GENESIS 15:11  And when the fowls came down upon the carcases, Abram drove them  away.

GENESIS 15:12  And when the sun was going down, a deep sleep fell upon Abram; and,  lo, an horror of great darkness fell upon him.

GENESIS 15:13  And he said unto Abram, Know of a surety that thy seed shall be a  stranger in a land that is not their's, and shall serve them; and they shall  afflict them four hundred years;

GENESIS 15:14  And also that nation, whom they shall serve, will I judge: and  afterward shall they come out with great substance.

GENESIS 15:15  And thou shalt go to thy fathers in peace; thou shalt be buried in a  good old age.

GENESIS 15:16  But in the fourth generation they shall come hither again: for the  iniquity of the Amorites is not yet full.

GENESIS 15:17  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.

GENESIS 15:18  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:

GENESIS 15:19  The Kenites, and the Kenizzites, and the Kadmonites,

GENESIS 15:20  And the Hittites, and the Perizzites, and the Rephaims,

GENESIS 15:21  And the Amorites, and the Canaanites, and the Girgashites, and the  Jebusites.
