'Lion' in the Bible

Will a lion roar in the thicket, when he has no prey? Does a young lion cry out of his den, if he has caught nothing?

The lion has roared. Who will not fear? The Lord Yahweh has spoken. Who can but prophesy?

Thus says Yahweh: "As the shepherd rescues out of the mouth of the lion two legs, or a piece of an ear, so shall the children of Israel be rescued who sit in Samaria on the corner of a couch, and on the silken cushions of a bed."

As if a man fled from a lion, and a bear met him; Or he went into the house and leaned his hand on the wall, and a snake bit him.
