'Disguised' in the Bible

But the Lord had said to Ahijah, “Jeroboam’s wife is coming soon to ask you about her son, for he is sick. You are to say such and such to her. When she arrives, she will be disguised.”

When Ahijah heard the sound of her feet entering the door, he said, “Come in, wife of Jeroboam! Why are you disguised? I have bad news for you.

So the prophet departed, and waited for the king by the way, and disguised himself with ashes upon his face.

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.
