'Everlasting Possession' in the Bible

And I give to thee, and to thy seed after thee, the land of thy sojourning, all the land of Canaan, for an everlasting possession; and I will be a God to them.

and he said to me, Behold, I will make thee fruitful and multiply thee, and I will make of thee a company of peoples; and will give this land to thy seed after thee for an everlasting possession.
