Moses admonishes the Israelites not to be lured by the heathen abominable practices of the Canaanites, and to remain true to the Torah; neither adding to nor subtracting from its laws. A person professing to be a prophet who claims to bring instructions from G‑d to worship idols must be put to death. This is true even if the individual performs supernatural acts or accurately predicts the future. This section also prescribes the death penalty for one who attempts to entice others to idolatry, and the catastrophic price paid by a city which has completely succumbed to idolatry.
