מלכים ב, פרק י״ז, פסוק ל״ז

The obligation to follow the commandments and reject idol worship is rooted deeply in the covenant established with God [ביאור שטיינזלץ]. This commitment is not a temporary arrangement. The requirement to keep the laws for all time serves as fundamental proof that the Torah is eternal. It was given as a permanent guide that will never change or be replaced by any other set of laws [רלב״ג].

Observing these commandments profoundly impacts how God interacts with a person. When someone follows the laws of the Torah, they step outside the ordinary rules of nature and the influence of the stars. Instead, they receive direct and exclusive care from God. Because of this personal attention, there is absolutely no need to fear other gods or worldly powers. A person under His direct watch is completely free from the control of any outside forces, removing all reason for fear [מלבי״ם].
