'Disguise' in the Bible

Jeroboam said to his wife, "Please get up and disguise yourself so that they will not know that you [are] the wife of Jeroboam, and go [to] Shiloh. Look, Ahijah the prophet is there, and he spoke concerning me [before I became] king over this people.

Then the king of Israel said to Jehoshaphat, "[I will] disguise myself and go into the battle, but you wear your robes." So the king of Israel disguised himself, and he went into the battle.

And the king of Israel said to Jehoshaphat, "I will disguise myself and go into battle, but you, wear your garments." So the king of Israel disguised himself, and they went to war.

Therefore [it is] not a great thing if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds.
