‘It is only through the marriage to Ruth that Naomi and her land are redeemed, just as there are numerous prophecies that only through the “cleaving” of the Gentiles to the Messiah will Israel be redeemed (Joseph’s story, Isa. 11:10, Amos 9:15, etc.).’
Isaiah 11
10And in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious.
Amos 9
15And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God.
