2 Kings 1:15-16

15And the angel of Yhwh said unto Elijah, Go down with him: be not afraid of him. And he arose, and went down with him unto the king.

16And he said unto him, Thus saith Yhwh, Forasmuch as thou hast sent messengers to enquire of Baal–zebub the god of Ekron, is it not because there is no God in Israel to enquire of his word? therefore thou shalt not come down off that bed on which thou art gone up, but shalt surely die.
