Jamieson, Fausset & Brown, on 2Kgs 6:30

“When the king heard this, he rent his garments, and passed by upon the wall. And all the people saw the haircloth which he wore within next to his flesh.”

“had sackcloth within upon his flesh--The horrid recital of this domestic tragedy led the king soon after to rend his garment, in consequence of which it was discovered that he wore a penitential shirt of haircloth. It is more than doubtful, however, if he was truly humbled on account of his own and the nation's sins; otherwise he would not have vowed vengeance on the prophet's life. The true explanation seems to be, that Elisha having counselled him not to surrender, with the promise, on condition of deep humiliation, of being delivered, and he having assumed the signs of contrition without receiving the expected relief, regarded Elisha who had proved false and faithless as the cause of all the protracted distress.”
