'Disguise' in the Bible
And Jeroboam said to his wife, Arise, I pray thee, and disguise thyself, that thou not be known to be the wife of Jeroboam, and go to Shiloh, for Ahijah the prophet is there, who told me that I should be king over this people.
But the LORD had said unto Ahijah, Behold, the wife of Jeroboam shall come to consult thee regarding her son, who is sick; thus and thus shalt thou say unto her, for it shall be, when she comes, that she shall come in disguise.
And it was so, when Ahijah heard the sound of her feet as she came in at the door, that he said, Come in, wife of Jeroboam; why art thou in disguise? For I am sent to thee with heavy tidings.
And the king of Israel said unto Jehoshaphat, I will disguise myself and enter into the battle, but put thou on thy robes. And the king of Israel disguised himself and went into the battle.
