'Lion' in the Bible

Roar doth a lion in a forest and prey he hath none? Give out doth a young lion his voice from his habitation, If he hath not caught?

A lion hath roared -- who doth not fear? The Lord Jehovah hath spoken -- who doth not prophesy?

As when one fleeth from the face of the lion, And the bear hath met him, And he hath come in to the house, And hath leant his hand on the wall, And the serpent hath bitten him.
