'Perisheth' in the Bible

Who is the wise man, that may understand this? and who is he to whom the mouth of the LORD hath spoken, that he may declare it, for what the land perisheth and is burned up like a wilderness, that none passeth through?

Woe be unto thee, O Moab! the people of Chemosh perisheth: for thy sons are taken captives, and thy daughters captives.
