'Disguise' in the Bible

Jeroboam said to his wife, “Go disguise yourself, so they won’t know that you’re Jeroboam’s wife, and go to Shiloh. Ahijah the prophet is there; it was he who told about me becoming king over this people.

But the king of Israel said to Jehoshaphat, “I will disguise myself and go into battle, but you wear your royal attire.” So the king of Israel disguised himself and went into battle.
