1 Kings 22:6, 15

Then the king of Israel gathered the prophets together, about four hundred men, and said unto them, Shall I go against Ramoth-gilead to battle, or shall I forbear? And they said, Go up; for the Lord shall deliver it into the hand of the king.

So he came to the king. And the king said unto him, Micaiah, shall we go against Ramoth-gilead to battle, or shall we forbear? And he answered him, Go, and prosper: for the LORD shall deliver it into the hand of the king.
