Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.
Ver. 3. Thou shalt not hearken.] Heretics have their pythanology, their good words and fair speeches, wherein they can vent a spittle of diseased opinions, and whereby they deceive the hearts of the simple. Rom 16:18 It is not safe, therefore, to hear them, or hold discourse with such, lest they insinuate and infect us, as the Montanists did Tertullian; as the Valentinians did various well-affected Christians; as Acacius the heretic did Anastasius, second Bishop of Rome, A.D., 497, who sought to rectify him. It is reported of Placilla the good Empress, that when Theodosius, senior, desired to confer with Eunomius, she dissuaded her husband very earnestly, lest being perverted by his speeches he might fall into heresy a "Keep thee far from an evil matter," saith Solomon. "Mark those that make divisions, and avoid them," saith Paul. Rom 16:17 And again, "There are many unruly and vain talkers and deceivers, …, whose mouths must be stopped," &c. Tit 1:11
