In this chapter the Israelites are taught how to discern a false prophet, shun and punish him, De 13:1, what to do with enticers to idolatry, not only not to consent to them, but, without favour and affection to them, endeavour to bring them to just punishment, and be the first that should inflict it on them, De 13:6 and how to behave towards a city drawn into idolatry, as to inquire the truth of it; then make war against it; destroy all in it, men, women, children, and cattle; and burn the spoil of it, and suffer not anything at all belonging to it to cleave unto them, De 13:12.
Ver. 1. If there arise among you a prophet,.... A false prophet, a lying prophet, as the Targum of Jonathan; one that pretends to be a true prophet, and to be sent of God, and to come from him with a message from him, a new revelation or doctrine, or in his name, to foretell things to come; the former is chiefly meant.
Such prophets did arise in Israel before the time of Christ, and have since arose under the Christian name; see 2Pe 2:1,or a dreamer of dreams; the same with the prophet, only to be distinguished by the different manner of their having the mind and will of God revealed to them, pretended to; either by vision or by dream, which were the two usual ways in which the Lord spake to the true prophets, Nu 12:6 so that the prophet is one who pretended he had a vision from the Lord, and the dreamer one that had a dream from him, or something revealed to him in a dream; and dreams are sometimes used for false doctrines, vain, deceitful, and illusory; see Jer 23:25.
The Targum of Jonathan calls him"a dreamer of a dream of pride:''such persons are generally prompted by the pride of their own hearts to take such a method to make themselves famous and respected among men; and usually bring such doctrines with them which are agreeable to the pride and vanity of human nature:and giving thee a sign or a wonder; for the confirmation of his mission and doctrine; such as Moses wrought before the children of Israel and before Pharaoh.
