And the same John had his raiment of camel's hair--woven of it. and a leathern girdle about his loins--the prophetic dress of Elijah (Kg2 1:8; and see Zac 13:4). and his meat was locusts--the great, well-known Eastern locust, a food of the poor (Lev 11:22). and wild honey--made by wild bees (Sa1 14:25-26). This dress and diet, with the shrill cry in the wilderness, would recall the stern days of Elijah.
