'Green Pastures' in the Bible

Behold, like as the Lion cometh up from the pleasant meadows of Jordan unto the green pastures of Etham, so will I drive him, and make him run against her. But who is the young man that I will ordain thereto? Who is like unto me? What is he that will strive with me? What shepherd may stand in my hands?

Behold, like as the Lion cometh up from the pleasant meadows of Jordan unto the green pastures of Ethan, so will I drive them forth, and make them run against her. But whom shall I choose out, and ordain to such a thing? For who is like me, or who will strive with me? Or what shepherd may stand against me?
