'Lion' in the Bible

Will a lion roar in the forest, when he hath no prey? will a young lion cry out of his den, if he have taken nothing?

The lion hath roared, who will not fear? the Lord GOD hath spoken, who can but prophesy?

Thus saith the LORD; As the shepherd taketh out of the mouth of the lion two legs, or a piece of an ear; so shall the children of Israel be taken out that dwell in Samaria in the corner of a bed, and in Damascus in a couch.

As if a man did flee from a lion, and a bear met him; or went into the house, and leaned his hand on the wall, and a serpent bit him.
