Isaiah 16:5 And in mercy shall the throne be established: And he shall sit upon it in truth in the tabernacle of David, Judging, and seeking judgment, and hasting righteousness.
Moab wants help from Jerusalem, but they must realize that Jerusalem belongs to God. They must acknowledge the God of Heaven. God had established the throne there. Jesus will one day sit on this throne. The throne would be a place to do right. To get help there you will have to recognize the God of Heaven. You can’t come on your own terms but must come humbly recognizing Him for who He is.
