The establishment of the covenant at Mount Sinai reaches its climax in a public, monumental moment where the Israelites formally ratify their commitment to God and His laws. At the center of this ceremony is a written document read aloud by Moses, though commentators differ on its exact contents. The primary approach among commentators is that this book contained the specific commandments and laws Moses had just recorded, serving as the foundation of their new covenant [ספורנו, רשב״ם, רלב״ג, שטיינזלץ, אבן עזרא]. Conversely, others suggest it was a broader historical text encompassing the entire Torah from the creation of the world in Genesis up to the laws recently given at Marah [רש״י, מזרחי, רא״ש, הכתב והקבלה]. Further traditions propose that the document contained the detailed intricacies of the Ten Commandments [פענח רזא], the specific sections outlining blessings and curses [חזקוני], or simply a brief, concise charter serving as a formal declaration of their acceptance [קאסוטו].
The act of reading this document aloud to the nation served several vital purposes. Primarily, it transitioned the Israelites from a mere oral agreement to a binding, formal written commitment [רש ר הירש, שטיינזלץ]. The public recitation ensured absolute transparency, verifying that the people fully understood the responsibilities they were accepting so they would not feel deceived, thereby testing their final, informed consent [ספורנו, רלב״ג]. Furthermore, if the text included the historical narratives of their ancestors, hearing these stories taught the Israelites a profound lesson about their new spiritual reality. While acts of goodness and kindness were natural traits inherited from Abraham, Isaac, and Jacob, from this moment forward, such deeds had to be performed out of a Divine command for the sake of Heaven, rather than relying solely on human inclination [העמק דבר].
The immediate and absolute response of the people, committing first to do and then to hear, became an enduring symbol of faith, loyalty, and devotion. On a basic level, this declaration meant they would immediately fulfill the commandments they had already been given, while remaining attentive and obedient to whatever God would command in the future [רשב״ם, חזקוני, אבן עזרא]. On a deeper level, commentators highlight the profound contrast between action and hearing. The commitment to act refers to the physical fulfillment of the commandments, whereas the desire to hear represents internal understanding, belief in the heart, and intellectual study [ביאור יש״ר, שטיינזלץ, קונטרס חיבה יתירה].
By prioritizing action before understanding, the Israelites expressed a total surrender to God, showing a readiness to fulfill His will unconditionally, even before grasping the underlying reasons. Yet, their explicit desire to also hear demonstrates that they did not settle for blind obedience. Instead, they aspired to learn, to understand, and to fully engage both their intellect and emotions in serving God [חומש קה״ת, קונטרס חיבה יתירה]. Other perspectives suggest that the commitment to hear specifically refers to the study of the Oral Torah, which is essential for knowing how to properly execute the written laws [רש ר הירש]. Alternatively, it represents a dual acceptance, taking on the yoke of practical commandments alongside the distinct, independent commandment of Torah study [בית הלוי, פרדס יוסף].
Ultimately, prioritizing action over explanation is considered the pinnacle of Israelite faith. By doing so, the people adopted the nature of the ministering angels, who instinctively fulfill God's word before seeking to understand it. In merit of walking with such pure innocence, love, and absolute trust in God, the Israelites were spiritually adorned with two crowns corresponding to their dual promise, symbolizing the crowns of priesthood and kingship. Through this profound devotion, they earned the title of God's firstborn and achieved a transcendent level of freedom from the Angel of Death [תורה תמימה, חתם סופר].
