'Disguise' in the Bible

Jeroboam said to his wife, “Please get up and disguise yourself, so that people will not know that you are Jeroboam’s wife, and go to Shiloh. Ahijah the prophet is there, the one who told me that I would be king over this people.

The king of Israel said to Jehoshaphat, “I will disguise myself and enter the battle, but you put on your [royal] clothing.” So the king of Israel disguised himself and went into the battle.
