'Disguise' in the Bible

And Jeroboam said to his wife, Arise, I pray thee, and disguise thyself, that thou be not known to be the wife of Jeroboam; and get thee to Shiloh: behold, there is Ahijah the prophet, which told me that I should be king over this people.

But the Lord had told Ahijah, "Look, Jeroboam's wife is coming to find out from you what will happen to her son, for he is sick. Tell her so-and-so. When she comes, she will be in a disguise."

And the king of Israel said unto Jehoshaphat, I will disguise myself, and enter into the battle; but put thou on thy robes. And the king of Israel disguised himself, and went into the battle.
