1 Kings 22:6-12

6And the king of Israel assembled the prophets, about four hundred men, and said to them, Shall I go against Ramoth-Gilead to battle, or shall I forbear? And they said, Go up, and the Lord will give it into the king's hand.

7But Jehoshaphat said, Is there not here a prophet of Jehovah besides, that we might inquire of him?

8And the king of Israel said to Jehoshaphat, There is yet one man by whom we may inquire of Jehovah; but I hate him, for he prophesies no good concerning me, but evil: [it is] Micah the son of Imlah. And Jehoshaphat said, Let not the king say so.

9Then the king of Israel called a chamberlain, and said, Fetch quickly Micah the son of Imlah.

10And the king of Israel and Jehoshaphat the king of Judah, having put on their robes, sat each on his throne, in the open place at the entrance of the gate of Samaria; and all the prophets prophesied before them.

11And Zedekiah the son of Chenaanah made for himself horns of iron, and he said, Thus saith Jehovah: With these shalt thou push the Syrians, until thou have exterminated them.

12And all the prophets prophesied so, saying, Go up to Ramoth-Gilead, and prosper; for Jehovah will give it into the king's hand.
