'Lions' in the Bible

Where is now the den of the lions, and the feeding-place of the young lions, where the lion, the lioness, and the lion's whelp walked, and none made them afraid?

Behold, I am against thee, saith Jehovah of hosts: and I will burn her chariots into smoke; and the sword shall devour thy young lions, and I will cut off thy prey from the earth; and the voice of thy messengers shall no more be heard.
