'Cruel' in the Bible

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.
