שמות, פרק י״ט, פסוק כ״ה

After the intense storm of lightning and the blast of the horn, a profound silence falls over nature. This sudden stillness serves as a dramatic preparation for the giving of the Torah and the hearing of the Ten Commandments [קאסוטו]. Following the divine command, Moses descends to the Israelites, taking his place among them as they await the revelation [מלבי"ם, בכור שור].

Although the narrative notes that Moses spoke to the people, it leaves out the exact words he said in that moment. The primary approach among commentators is that he delivered a severe warning to both the Israelites and the priests. He cautioned them to respect the boundaries set around the mountain, warning that anyone who broke through would face death [רש"י, רשב"ם, ספורנו, שד"ל]. Furthermore, he made it clear that only he and Aaron were permitted to ascend [חזקוני]. While the text does not explicitly record their next steps, as soon as Moses finished delivering this warning, he and Aaron returned to their designated places on the mountain. This action is omitted from the narrative because it is clearly understood from God's previous instructions, setting the stage for the divine speech that followed immediately afterward [אבן עזרא, קאסוטו, ביאור שטיינזלץ].

With all preparations complete, the Ten Commandments begin, establishing the foundation of the moral and religious structure. These laws are divided into two distinct parts. The first five primarily focus on the relationship between humanity and God, noting that honoring one's parents is also a way of honoring the Creator. The final five address the relationship between people, and notably, God's name is absent from this section [ביאור שטיינזלץ]. As these laws were delivered, Moses stood between God and the Israelites, acting as a mediator. A shift in the language of the commandments reveals how they were heard. The transition from God speaking in the first person to being referred to in the third person indicates that the Israelites heard the first two commandments directly from God Himself, while they received the remaining commandments through Moses acting as His messenger [בכור שור].
