פּירוש אויף דברים 9:9

ואשב בהר — The verb ישב here means only "staying" (not "sitting"; it means: I stayed on the mountain) (Megillah 21a).

בעלותי ההרה, “while I ascended the Mountain.” This occurred on the first day of the week, the seventh day of the month of Sivan. [That is, Moses ascended Mount Sinai on the day following the Revelation which was on the Sabbath, the sixth of Sivan. Ed.]

לוחות אבנים, “Tablets hewn of stone.” Anyone who does not make his jaws hard as stone in order to study Torah, will not truly merit the Torah. Or; most death penalties decreed by the Torah involve the stoning of the victim. Still another interpretation: the Jewish people received the Tablets through the merit of Yaakov who has been described as אבן ישראל משם רועה, “from thence the shepherd, stone of Israel.” (Genesis 49,24) A further interpretation; it is due to the merit of the Temple.” Rabbi Shimon says it is because of the merit of the King Messiah. He bases himself on a verse in the Book of Daniel: 2,34, חזה הוית עד די אתגזרת אבן די לא בידין, “as you watched a stone was hewn without hands;” (compare Tanchuma, section 10 on our portion)
