פּירוש אויף שמות 34:32

ואחרי כן נגשו AND AFTERWARDS [THE CHILDREN OF ISRAEL] STEPPED NIGH — After he (Moses) had taught the elders he used again to teach the section or the single Halacha in question to the Israelites. The Rabbis have taught: How was the system of teaching? Moses used to learn the law from the mouth of the Almighty; Aaron entered and Moses taught him his lesson. Now Aaron moved away and took his seat to the left of Moses. Then his (Aaron’s) sons entered and Moses taught them their lesson. They moved away and Eleazar took his seat to the right of Moses, whilst Ithamar sat down at Aaron’s left. The elders then entered and Moses taught them their lesson. The elders moved away and took their seat at the side. Finally the whole people entered and Moses taught them their lesson. Consequently what was taught came into the possession of the whole people once, into the possession of the elders twice, into the possession of Aaron’s sons thrice and into Aaron’s possession four times etc. — as it is stated in Eruvin 54b.

את כל אשר דבר ה' אתו בהר סיני, “all the commandments that G-d had spoken to him about while he had been on Mount Sinai on his first and third stay on the Mountain, as well as all the commandments that He had communicated to him from Nissan when they had left Egypt until the twentieth of Iyar in the second year when they broke camp around the Mountain. However, according to the Talmud in tractate Gittin folio 60, the written Torah, i.e. in scroll form, he wrote down personally, one parchment at a time. When Moses made ready to leave this earth, he arranged these parchments in the order in which we read them nowadays according to the order he considered appropriate.

ויצום את כל אשר דבר ה' אתו, the construction of the Tabernacle, the garments of the priests, the mandatory contribution of the males from 20 to 60 years of age amounting to a half shekel per head.
