'Fierce' in the Bible

“For behold, I am raising up the Chaldeans,That fierce and impetuous peopleWho march throughout the earthTo seize dwelling places which are not theirs.

They are fierce and terrifying;their views of justice and sovereigntystem from themselves.

Their horses also are swifter than the leopards, and are more fierce than the evening wolves: and their horsemen shall spread themselves, and their horsemen shall come from far; they shall fly as the eagle that hasteth to eat.
