There's A Cancerous Growth Within (Pride)

In chapter 15 and 16 The Prophet tells of the desrtuction of Moab, which was mainly about the Pride of The Moabite. These characteristics are those of the unconverted, that don't crucify the flesh but hold on to the very thing that causes God to resist them, that is Pride. The very same people God would not allow Israel to inhabit their land, whom was very inhospitable to them.
