14 ¶ And the LORD said unto Abram, after that Lot was separated from him, Lift up now thine eyes, and look from the place where thou art northward, and southward, and eastward, and westward: 15 For all the land which thou seest, to thee will I give it, and to thy seed for ever. 16 And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered. 17 Arise, walk through the land in the length of it and in the breadth of it; for I will give it unto thee. 18 Then Abram removed his tent, and came and dwelt in the plain of Mamre, which is in Hebron, and built there an altar unto the LORD.
Abram is the physical progenitor of the Jewish people, the Arab, and others and he and his seed were promised a dwelling place on earth.
15 For all the land which thou seest, to thee will I give it, and to thy seed for ever.
God states that eventually Abram’s descendants will be innumerable and not able to be counted. The question asks itself whether or not this is referring to only Abram’s seed by the promise of descendants through a barren Sarai or does this include any and all of his descendants, his seed?
This is a physical promise of physical territory, land. This is a grant, a promise, and a covenant of land given to the descendants of a man who has pleased his Creator. This will become an important issue in a few chapters, one we must sort out to understand God’s future plans.
Genesis 25:5 And Abraham gave all that he had unto Isaac.
Again, Abram builds an altar to the Lord.
