'Frowardness' in the Bible

Who rejoice to do evil, and delight in the frowardness of the wicked;

Frowardness is in his heart, he deviseth mischief continually; he soweth discord.

The mouth of the righteous uttereth wisdom, And the tongue of frowardness is cut out.

The lips of the righteous know what is acceptable: but the mouth of the wicked speaketh frowardness.
