Therefore my heart shall sound for Moab like pipes,.... That are sounded on mournful occasions, as at funerals, and the like; see Mt 9:23. This the prophet said, as Kimchi observes, in the person of the people, the inhabitants of Moab; whose hearts would yearn and sound for the calamities of their country like the doleful sound of minstrels.
So the Targum,"therefore the Moabites shall sound in their hearts like a harp:''and my heart shall sound like pipes for the men of Kirheres; as for the country of Moab in general, so for this principal city, and the inhabitants of it, in particular; See Gill on "Isa 16:11";because the riches [that] he hath gotten is perished; either Moab or Kirheres; the abundance of goods they had got together were now lost, falling into the hands of the enemy; and which was matter of lamentation.
The Targum is,"for the rest of their substance they had got were spoiled.'
