'Lions' in the Bible

Where is the den of the lionsAnd the feeding place of the young lions,Where the lion, lioness and lion’s cub prowled,With nothing to disturb them?

“Behold, I am against you,” declares the Lord of hosts. “I will burn up her chariots in smoke, a sword will devour your young lions; I will cut off your prey from the land, and no longer will the voice of your messengers be heard.”
