Ahab sent messengers to all the Israelites and had the prophets assemble at Mount Carmel.

Ahab told Jezebel all that Elijah had done, including a detailed account of how he killed all the prophets with the sword.

One of the members of the prophetic guild, speaking with divine authority, ordered his companion, “Wound me!” ¹  But the man refused to wound him.

So the king of Israel assembled about four hundred prophets and asked them, “Should I attack Ramoth Gilead or not?” ¹  They said, “Attack! The sovereign one ²  will hand it over to the king.”

Now the king of Israel and King Jehoshaphat of Judah were sitting on their respective thrones, ¹  dressed in their robes, at the threshing floor at the entrance of the gate of Samaria. ²  All the prophets were prophesying before them.

Now the messenger who went to summon Micaiah said to him, “Look, the prophets are in complete agreement that the king will succeed. ¹  Your words must agree with theirs; you must predict success.” ²
