Charles Ellicott Commentary 1 Kings 22:30

"And the king of Israel said unto Jehoshaphat, I will disguise myself, and go into the battle; but put thou on thy robes. And the king of Israel disguised himself, and went into the battle." — 1 Kings 22:30 (ASV)

I will disguise myself. The precaution of Ahab is almost ludicrously characteristic of his temper of half-belief and half-unbelief. In itself, it is, of course, plainly absurd to believe that God’s judgment has in all probability been pronounced, and yet to suppose that it can be averted by so puerile a precaution. But, as experience shows, it is no less true to human nature on that account, especially such a nature as his, always halting between two opinions.
