Isaiah 32:7

The instruments also of the churl are evil: he deviseth wicked devices to destroy the poor with lying words, even when the needy speaketh right.

The churl is the churlish and ungenerous person. The instruments or means at his disposal are evil. He devises deceitful schemes aimed at harming and destroying the poor through lying words. He carries out this false attack even when the needy speak what is right and their cause is just.
