Talmud sobre Exodo 30:30

The Torah was given at Sinai through Moses' hands, as it says (Deuteronomy 5:19), "He wrote them on two stone tablets, and He gave them to me." And then later it says (Leviticus 26:46), "These are the decrees and the laws and the teachings that the Eternal gave, through Moses on Mount Sinai, between Him and the children of Israel." The Torah that the Holy Blessed One gave to Israel was given only through Moses, as it says (Exodus 31:17), "Between Me and the children of Israel"; Moses merited to be a messenger between the children of Israel and the Omnipresent God. Moses prepared the inaugural ram and the anointing oil, and anointed Aaron and his sons with it all seven days of inauguration, and from it, all the high priests and kings are anointed. And Elazar burned the [red] heifer as a sin offering, with which impurities would be purified for generations. Rabbi Eliezer said: Great is this ritual, for it is practiced throughout the generations, just as Aaron and his sons were sanctified with this anointing oil, as it says (Exodus 30:30), "Anoint Aaron and his sons, and sanctify them to serve as priests.”
