What does 2 Kings 1:8 mean?

They told him, 'A man met us and said, "Go back to the king who sent you and tell him, 'This is what God says: Is there no God in Israel that you're sending messengers to Baal-zebub, the god of Ekron? Because of this, you won't get up from your bed. You're going to die.'"' 2 Kings 1:8 - Modern Text Bible

(The messengers repeat Elijah's message, making it clear that Ahaziah's fate is sealed because he sought help from a false god.)
