And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger,—literally, of thy sojournings (Genesis 12:9; Acts 7:5; Hebrews 11:9)—all the land of Canaan (vide Genesis 10:19),—for an everlasting possession.
Literally, for a possession of eternity; i.e. the earthly Canaan should be retained by them so long as the arrangement then instituted should continue, provided always they complied with the conditions of the covenant; and the heavenly Canaan should be the inheritance of Abraham's spiritual children forever (vide Genesis 9:16; Genesis 13:15).
And I will be their God. Literally, to them for Elohim (vide supra).
