Isaiah 11:6-9

And the wolf shall dwell with the lamb, and the leopard shall lie down with the kid, and the calf and the young lion and the fatted domestic animal together; and a little child shall lead them. And the cow and the bear shall feed side by side, their young shall lie down together, and the lion shall eat straw like the ox. And the sucking child shall play over the hole of the asp, and the weaned child shall put his hand on the adder's den. They shall not hurt or destroy in all My holy mountain, for the earth shall be full of the knowledge of the Lord as the waters cover the sea.
