What does 2 Kings 1:5 mean?

But an angel from God told Elijah the Tishbite, 'Go meet the messengers from Samaria's king and ask them, "Is there no God in Israel that you're going to consult Baal-zebub, the god of Ekron?"' 2 Kings 1:5 - Modern Text Bible

(God intervenes through Elijah, confronting Ahaziah's lack of faith and his reliance on foreign gods.)
