Isaiah 16:11:
Wherefore my bowels shall sound like an harp for Moab, and mine inward parts for Kirharesh.
When Moab is used in this particular context in the Bible most people think it refers to a mountainous strip of land in Jordan. In actual fact it is more likely an acronym for Massive Ordinance Air Blast.
