(38) Ashes upon his face.--It should be a "bandage over his head," to cover his face, and to accord with the appearance of a wounded soldier. Unless the wound had some symbolic significance in application to Ahab or Israel, it is difficult to see what purpose it could serve.

Verse 38. - So the prophet departed, and waited for the king by the way, and disguised himself with ashes upon his face. [Rather, a bandage upon his eyes. אֲפֵר there can be no doubt, denotes some sort of covering (LXX. τελαμών), and is probably the equivalent of עֲפֵר. Ashes cannot be put on the eyes, and even on the head would be but a poor disguise. This bandage was at the same time in keeping with the prophet's role as a wounded man, and an effective means of concealment. It would almost seem as if this prophet was personally known to the king.]

20:31-43 This encouragement sinners have to repent and humble themselves before God; Have we not heard, that the God of Israel is a merciful God? Have we not found him so? That is gospel repentance, which flows from an apprehension of the mercy of God, in Christ; there is forgiveness with him. What a change is here! The most haughty in prosperity often are most abject in adversity; an evil spirit will thus affect a man in both these conditions. There are those on whom, like Ahab, success is ill bestowed; they know not how to serve either God or their generation, or even their own true interests with their prosperity: Let favour be showed to the wicked, yet will he not learn righteousness. The prophet designed to reprove Ahab by a parable. If a good prophet were punished for sparing his friend and God's when God said, Smite, of much sorer punishment should a wicked king be thought worthy, who spared his enemy and God's, when God said, Smite. Ahab went to his house, heavy and displeased, not truly penitent, or seeking to undo what he had done amiss; every way out of humour, notwithstanding his victory. Alas! many that hear the glad tidings of Christ, are busy and there till the day of salvation is gone.So the prophet departed, and waited for the king by the way,.... As he went from Aphek, the place where the battle had been fought, to Samaria, his royal seat:

and disguised himself with ashes upon his face; the Targum is, he covered his eyes with a vail, or piece of cloth, which he wrapped about his head, as men do when they have got a wound or bruise in such a part, which seems very probable; for had he besmeared his face with ashes, clay, or dust, or any such thing, he could not so easily have got it off, as in 1 Kings 20:41.
