Hebrews 11:36-38

And others had trial of cruel mockings and scourgings, yea, moreover of bonds and imprisonment: 

They were stoned, they were sawn asunder, were tempted, were slain with the sword: they wandered about in sheepskins and goatskins; being destitute, afflicted, tormented; 

(Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth.
