Elvis Presley's "(There'll Be) Peace in the Valley (For Me)"

To-day I listened to an Elvis Christmas album, and I noticed a Biblical reference in the second verse of "(There'll Be) Peace in the Valley (For Me)":

Well, the bear will be gentle, and wolves will be tame
And the lion shall lie down by the lamb, oh, yes
And the beast from the wild shall be led by a child
And I'll be changed, changed from this creature that I am, oh, yes

There are more than a few similarities between this and part of Isaiah:

The wolf shall dwell with the lamb, and the leopard shall lie down with the young goat, and the calf and the lion and the fattened calf together; and a little child shall lead them.  The cow and the bear shall graze; their young shall lie down together; and the lion shall eat straw like the ox. - Isaiah 11:6-7

All of the same animals are mentioned, as is their being led by a child; it's just in a different order.
