Hebrews 11:38 Meaning

36And others had trial of cruel mockings and scourgings, yea, moreover of bonds and imprisonment:

37They were stoned, they were sawn asunder, were tempted, were slain with the sword: they wandered about in sheepskins and goatskins; being destitute, afflicted, tormented;

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

39And these all, having obtained a good report through faith, received not the promise:

40God having provided some better thing for us, that they without us should not be made perfect.
