'Disguise' in the Bible

so Jeroboam suggested to his wife, "Get up, disguise yourself so that no one will know that you're Jeroboam's wife, and go to Shiloh where the prophet Ahijah lives. He's the one who told me that I would be king over this people.

The king of Israel suggested to Jehoshaphat, "I'll go into battle in disguise, but you keep your royal uniform on." So the king of Israel disguised himself and they both went into the battle.
