'Disguise' in the Bible

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

The king of Israel said to Jehoshaphat, “I will disguise myself and go into battle, but you put on your robes.” So the king of Israel disguised himself, and they went into battle.

Therefore it is not surprising if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds.
