Micaiah in Wikipedia

Micaiah son of Imlah is a prophet in the Hebrew Bible. He is not the same as the titular prophet of the Book of Micah, also called "The Morasthite" to distinguish him from Micaiah. Today Micaiah is a rare name and it is still debated if it is unisex or for men only. Micaiah's prophecy. Under duress, Micaiah gave a negative prophecy to Ahab regarding his fate if Israel's army attacked Ramath Gilead. The prophecy suggested Ahab would be killed in battle. As a result of this prophecy, Ahab ordered Micaiah imprisoned (1 Kings 22:8 and 2 Chronicles 18:16). Perhaps concerned about Micaiah's prophecy, Ahab disguised himself in battle rather than lead his troops openly as their king. However, Ahab died in battle true to Micaiah's prophecy, and contrary to the word of 400 false prophets, all of whom encouraged Ahab to attack with a prediction of victory. The prophecy is probably the earliest example in the Hebrew Bible of a representation of a heavenly throne room. It is not clear whether the prophecy represents Micaiah's own belief or a depiction of the beliefs of Ahab's prophets such as Zedekiah the son of Chenaanah, who struck him after the prophecy (1 Kings 22:24)[1]
