Mark 1 verse 6

And they answered him, He was an hairy man, and girt with a girdle of leather about his loins. And he said, It is Elijah the Tishbite.

And it shall come to pass in that day, that the prophets shall be ashamed every one of his vision, when he hath prophesied; neither shall they wear a rough garment to deceive:

And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey.

Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.
