Charles Ellicott Commentary Isaiah 16:11

"Wherefore my heart soundeth like a harp for Moab, and mine inward parts for Kir-heres." — Isaiah 16:11 (ASV)

My bowels shall sound like an harp ... — The context leaves it uncertain whether the speaker is the prophet as in Isaiah 16:9, or Jehovah as in Isaiah 16:10. The former seems, perhaps, the most natural. On the other hand, the very phrase is used of the compassion of Jehovah in Isaiah 63:15. The “bowels,” as in modern language the “heart,” were regarded as the seat of the emotions, and as such they vibrate, like the chords of the harp or lyre (kinnûr) used at funerals, with the thrills of pity.
