'Lion' in the Bible

Will a lion roar in the forest without having found its prey? Will a young lion cry from its den without having caught anything?

A lion has roared! Who will not fear? The Lord GOD has spoken! Who will not prophesy?

It will be like a man who runs from a lion, only to encounter a bear; or who comes home, leans his hand against a wall, and a serpent bites him!
