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 likethe ox. And thesucking child shall playonthehole 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 L, as the waters cover the sea.

-Bible (Old Testament)
Jeremiah13:23.

That will not bring back the things we love: the high, clear days and the blue icecaps on the mountains; the lines of white poplars fluttering in the wind, and the long white prayer flags† Nor shall we get back the smell of the beanfields; the sweet, resinous smell of deodar wood burning, or the whiff of a snow leopard at14,000 feet. Never. Never. Never.

-Chatwin, Bruce
  Introduction to Robert Byron's The Road to Oxiana.

Subjects choose me† I lie in wait like a leopard on a branch-strained metaphor.
