Therefore my bowels shall sound like a harp for Moab. Assuming the character of a Moabite, the Prophet again describes excessive lamentation, proceeding from grief so intense that even the bowels make a distressing noise; for by the sign he intended to point out the reality. We have formerly explained the object of those lively descriptions, which is, to bring the events, as it were, before our eyes, and to lead us to entertain stronger hopes of those things which appear to go beyond all belief. By again naming Kir-Hareseth, the chief city, and thus taking a part for the whole, he describes the destruction of the whole country.

Wherefore my bowels - This is also an expression of the deep grief of the prophet in view of the calamities which were coming upon Moab. The "bowels" in the Scriptures are everywhere represented as the seat of compassion, pity, commiseration, and tender mercy Genesis 43:30 : 'His bowels did yearn upon his brother' - he deeply felt for him, he greatly pitied him 1-Kings 3:26; Psalm 25:6; Proverbs 12:10; Song 5:4; Isaiah 63:15; Jeremiah 4:19; Jeremiah 31:20; Philippians 1:8; Philippians 2:1. In classic writers, the word 'bowels' denotes the "upper" viscera of victims - the heart, the lungs, the liver, which were eaten during or after the sacrifice (Robinson, "Lex.," on the word σπλάγχνον splangchnon). In the Scriptures, it denotes the "inward parts" - evidently also the upper viscera, regarded as the seat of the emotions and passions. The word as we use it - denoting the lower "viscera" - by no means expresses the sense of the word in the Scriptures, and it is this change in the signification which renders the use of the very language of the Bible unpleasant or inappropriate. We express the idea by the use of the word "heart" - the seat of the affections.
Shall sound like an harp - The "bowels" are represented in the Scriptures as affected in various modes in the exercise of pity or compassion. Thus, in Lamentations 1:20, Jeremiah says, 'My bowels are troubled' (see Lamentations 2:1; Jeremiah 31:20). Job Job 30:27, says, 'My bowels boiled, and rested not;' there was great agitation; deep feeling. Thus, Jeremiah 4:19 :
My bowels! My bowels! I am pained at my very heart.
My heart "maketh a noise" in me.
So Isaiah 63:15 : 'Where is the sounding of thy bowels and mercies?' The word 'sound' here means to make a tumultuous noise; and the whole expression here denotes that his heart was affected with the calamities of Moab as the strings of the harp vibrate when beaten with the plectrum or the band. His heart was deeply pained and affected by the calamities of Moab, and responded to those calamities, as the strings of the harp did to the blow of the plectrum.
Mine inward parts - The expressions used here are somewhat analogous to ours of the "beating of the heart," to denote deep emotion. Forster says of the savages of the South Sea that they call compassion "a barking of the bowels."
For Kirharesh - (See the note at Isaiah 16:7.)

Wherefore my (m) heart shall sound like an harp for Moab, and my inward parts for Kirharesh.
(m) For sorrow and compassion.

Wherefore my bowels shall sound like a harp for Moab,.... Making a noise as the harp does, and a mournful one as that, when used at funerals; which it makes when it is stricken or played on with the hand, as these were, through the afflictive and punitive hand of God; and which, when stricken, causes a quavering of the strings, to which the inward trembling of the bowels is compared, and is very expressive of the prophet's sympathy, or those he personates; for, when one string of the harp is touched, the rest sound. For these words, as Kimchi says, are spoken in the language of the Moabites; those that survived lamenting the desolate state of their country, which must be very great and affecting; and to show that it was so is the design of the prophet's expressing himself after this manner; for if it was painful to him, it must be much more so to them; so the Targum,
"wherefore the bowels of the Moabites shall sound as a harp;''
of the sounding of the bowels, see Isaiah 63:15,
and mine inward parts for Kirharesh: the same with Kirhareseth, Isaiah 16:7 which being a principal city, the destruction of it was greatly laid to heart. The Targum is,
"and their heart shall grieve for the men of the city of their strength;''
it being a strong city, in which they placed their confidence; but being destroyed, and the inhabitants of it, it was very affecting, to which agrees Jeremiah 48:31.

bowels--in Scripture the seat of yearning compassion. It means the inward seat of emotion, the heart, &c. (Isaiah 63:15; compare Isaiah 15:5; Jeremiah 48:36).
sound . . . harp--as its strings vibrate when beaten with the plectrum or hand.

My bowels - Thro' compassion. In excessive grief, the bowels are sometimes rolled together, so as to make an audible noise.
