'Lions' in the Bible

The young lions roared upon him, and yelled, and they made his land waste: his cities are burned without inhabitant.

[The Lord rebukes Jeremiah for his impatience, saying] “If you have raced with men on foot and they have tired you out,Then how can you compete with horses?If you fall down in a land of peace [where you feel secure],Then how will you do [among the lions] in the [flooded] thicket beside the Jordan?

Israel is a scattered sheep; the lions have driven him away: first the king of Assyria hath devoured him; and last this Nebuchadrezzar king of Babylon hath broken his bones.

They shall roar together like lions: they shall yell as lions' whelps.
