With his mouth; by his corrupt communication, whereby he endeavours to draw him to error or wickedness. Through knowledge, to wit, of God, and of his word, which makes men wise, and discovers, and so prevents, the frauds of deceivers. Be delivered from the infection of the hypocrite's evil and crafty counsel.
