Rashi derives from this pasuk that one who worships idols is in reality turning away from the entire Torah. Rashi’s words seem superfluous. Obviously one who is an idol worshiper has no relationship with the Torah! Horav Y.D. Soloveitchik, z.l., explains this pasuk in the following manner. Some individual Jews who, despite their commitment to Torah observance, still believe in various forms of idol worship. Indeed, the Navi Sheker, the false prophet, uses Hashem’s Name in an effort to promulgate idolatry! This is a grave mistake. To believe in Hashem is to believe in nothing else. Hashem is the sole Supreme Being who created this world from nothing and guides every aspect of it at every moment. To deviate from this belief or to ascribe any form of collaboration to Him is pure blasphemy.
