1 Kings 18:16-20 ESV
So Obadiah went to meet Ahab, and told him. And Ahab went to meet Elijah.
When Ahab saw Elijah, Ahab said to him, “Is it you, you troubler of Israel?” And he answered, “I have not troubled Israel, but you have, and your father’s house, because you have abandoned the commandments of the LORD and followed the Baals. Now therefore send and gather all Israel to me at Mount Carmel, and the 450 prophets of Baal and the 400 prophets of Asherah, who eat at Jezebel’s table.”
So Ahab sent to all the people of Israel and gathered the prophets together at Mount Carmel.
