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 - the fraudulent (cf. Isaiah 32:5, note). This verse refers to the last clause of Isaiah 32:5 as Isaiah 32:6 referred to its first clause.
Even when the needy speaketh right - pleadeth a just cause (Isaiah 29:21). Spiritually, "the poor man's cause" is the divine doctrine, his rule of faith and practice.
