Isaiah 16

I think the prophesy about Moab's destruction is an interesting backdrop for a brief comment about Messiah's reign (vss 4-5). Maybe it was the faithlessness and hatred of Moab that was intended to be a contrasting background for the faithful and loving rule of Messiah. Moab displayed speed is flouting their arrogance while God's anointed will be quick to act rightly. The focus of the Promised One will be on eternal justice while the people of Moab were a self-serving people. Maybe I'm missing God's point, but like I said this is an interesting passage in which to describe the traits of the Christ.
