The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice’ den. They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.
Even wild animals will submit to the Messiah’s rule, making it possible for a nursing child to play by a den of snakes. One of the most glorious promises in all of the Bible is the second half of verse 9, giving the reason for the ideal conditions during the Millennial Kingdom – the whole earth will be full of the knowledge of God.
