Hebrews 11:33-39
Brethren: the saints through faith subdued kingdoms, wrought justice, obtained promises, stopped the mouths of lions, quenched the violence of fire, escaped the edge of the sword, recovered strength from weakness, became valiant in battle, put to flight the armies of foreigners: women received their dead raised to life again: but others were racked, not accepting deliverance, that they might find a better resurrection; and others had trial of mockeries and stripes, moreover also of bands and prisons: they were stoned, they were cut asunder, they were tempted, they wandered about in sheep-skins, and in goat-skins, being in want, distressed, afflicted of whom the world was not worthy: wandering in deserts, in mountains, and in dens, and in caves of the earth. And all these were found approved by the testimony of faith, in Christ Jesus our Lord.

Verse 37. Mhlon signifies a sheep; mhlwth signifies a sheep skin, with the wool on it. This, or a goat skin, was the usual covering of poor people, and as such was adopted by the ancient prophets, mortified to all the luxuries of life. Thus Elias is called vir pillosus, a hairy man, not for his beard or hair, but for his shaggy or hairy covering.
