'Perverseness' in the Bible

Who rejoice to do evil, And delight in the perverseness of evil;

In whose heart is perverseness, Who deviseth evil continually, Who soweth discord.

The lips of the righteous know what is acceptable; But the mouth of the wicked'speaketh perverseness.

The integrity of the upright shall guide them; But the perverseness of the treacherous shall destroy them.

A gentle tongue is a tree of life; But perverseness therein is a breaking of the spirit.
