'Cruel' in the Bible

Watch out! For I am bringing in the Chaldeans, that cruel and impetuous people, who sweep across the earth dispossessing people from homes not their own.

And their horses are quicker than leopards and their horsemen more cruel than evening wolves; they come from far away, like an eagle in flight rushing on its food.

A curse on the cruel and false one! the man full of pride, who never has enough; who makes his desires wide as the underworld! he is like death; he is never full, but he makes all nations come to him, getting all peoples together to himself.
