דברים, פרק ה׳, פסוק כ״ט

Following the overwhelming experience at Mount Sinai, the Israelites asked Moses to act as a mediator between them and God. This pivotal moment leads to a practical and binding expectation: absolute loyalty to God's instructions. Such faithfulness is the only path to securing a happy and fulfilling life, both in the present and in the future [רש״ר הירש].

There are different perspectives on the exact scope of this required loyalty. One approach suggests that the immediate focus is strictly on the Ten Commandments, which the Israelites heard directly from God, while the rest of the laws transmitted through Moses are addressed later [רמב״ן, הטור הארוך]. Conversely, other scholars emphasize that because the people explicitly appointed Moses as their messenger, everything he teaches carries the exact same weight as a direct divine decree. Therefore, every single Commandment must be observed with the very same awe and reverence as if it were spoken directly by God Himself [מלבי״ם, ביאור יש״ר, ביאור שטיינזלץ].

A natural concern arises that the sheer number of Commandments and their intricate details might feel like a heavy burden. To counter this, the focus shifts to the mindset behind the actions. Observing God's laws should stem from love and affection, rather than a desire for reward. When a person realizes that the Commandments are an expression of God's love, the feeling of burden disappears. The experience is compared to wearing a heavy, expensive pearl necklace; the wearer does not feel its physical weight because they are entirely focused on its immense value and beauty [אלשיך].

This deep commitment naturally leads to a strict warning against deviating from the prescribed path in any direction. In this context, turning to the right represents adding new rules to the Commandments, while turning to the left means subtracting from them [רלב״ג, ספורנו, אבן עזרא, אבי עזר]. There is a unique and subtle danger in adding to the law. A person might introduce new practices with the best of intentions, believing that their own logic can improve or expand upon the good. In reality, however, this damages the law and completely misses the Torah's original intent [ספורנו, רלב״ג]. This strict adherence is especially crucial regarding the duties between humanity and God, particularly those laws that defy human logic. In these matters, a person must not rely on their personal intellect but must hold firmly to the accepted tradition without wandering from it [העמק דבר].
