2 Kings 1:8

And they answered him, he was an hairy man
Either the hair of his head and beard were grown very long, having been much neglected for a great while; or he had an hairy garment on, either of goats' hair, such as the Chinese wear ^F6, whose women spin it, see ( Exodus 35:26 ) and of which garments are made; or of camels' hair, such as John the Baptist wore, who came in his spirit and power, and imitated him in his dress, being also, as Elijah here, girt with a girdle of leather about his loins:
for more expeditious travelling, not for warmth, the climate being hot: and he said, it is Elijah the Tishbite;
for he had seen him formerly in his father's court in this dress.
