For I will cast out the nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou shalt go up to appear before the Lord thy God thrice in the year. (Exodus 34:24)
The first promise of land made to Abraham and his seed is recorded in Gen. 12:5-7. Later this promise was widened to include the whole area between the “river of Egypt” and the Euphrates (Gen. 15:18; 1 Kings 4:21; 2 Chron. 9:26).
Beholding the incomparable superiority of Israel to all other nations, many would voluntarily unite themselves with God’s chosen people. Thus Israel’s borders would be enlarged until, eventually, “their kingdom should embrace the world” (COL 290). Jerusalem itself would stand forever (GC 19) and would become the metropolis of the entire earth (DA 577).
