2 Kings 1:6-8

6And they said to him, “There came a man to meet us, and said to us, ‘Go back to the king who sent you, and say to him, Thus says the LORD, Is it because there is no God in Israel that you are sending to inquire of Baal-zebub, the god of Ekron? Therefore you shall not come down from the bed to which you have gone up, but you shall surely die.’” 7He said to them, “What kind of man was he who came to meet you and told you these things?” 8They answered him, “He wore a garment of hair, with a belt of leather about his waist.” And he said, “It is Elijah the Tishbite.”
