Psalms 60:8

Moab would serve God as a washbasin; namely, it would be reduced to the status of a servant. God’s people would experience purification there as they fought this neighbor. God would throw His shoe toward Edom as a man threw his shoe toward his servant when he came home. Evidently this was commonly done in the ancient Near East. The Edomites, like the Moabites, were God’s servants, not His sons in the same sense that the Israelites were. The NIV’s translation, "Over Philistia I shout in triumph," pictures God announcing David’s victory over the Arameans to this enemy.
