Isaiah 11:6-9

In that day the wolf and the lamb will live together; the leopard will lie down with the baby goat. The calf and the yearling will be safe with the lion, and a little child will lead them all. The cow will graze near the bear. The cub and the calf will lie down together. The lion will eat hay like a cow. The baby will play safely near the hole of a cobra. Yes, a little child will put its hand in a nest of deadly snakes without harm. Nothing will hurt or destroy in all my holy mountain, for as the waters fill the sea, so the earth will be filled with people who know the LORD.
