2 Kings 1:15-16

15And the angel of the Lord said to Elijah, “Go down with him; do not be afraid of him.” So he arose and went down with him to the king.

16Then he said to him, “Thus says the Lord: ‘Because you have sent messengers to inquire of Baal-Zebub, the god of Ekron, is it because there is no God in Israel to inquire of His word? Therefore you shall not come down from the bed to which you have gone up, but you shall surely die.’ ”
