Therefore mine heart shall sound for Moab like pipes, and mine heart shall sound like pipes for the men of Kirheres: because the riches that he hath gotten are perished.
My heart shall sound for Moab - (notes, Isaiah 15:7; Isaiah 16:11).
Like pipes - a plaintive instrument, therefore used at funerals and in general mourning.
The riches that he hath gotten are perished - literally, the abundance ... that which is over and above the necessaries of life [superabundance, yitrat]. Grotius translates, 'They who have been left remaining shall perish;' they who have not been slain by the enemy shall perish by disease and famine.
