On the first day of the dedication of the Tabernacle, not lest than eight important sections of laws were communicated to Moses by God. As a reward for his piety, Aaron and his descendants to all eternity received the laws of sanctity, which are a special distinction of the priests, and these laws were revealed on this day. It was on this day, also, that Aaron and his sons received the gifts of the priests, for although even at the revelation on Sinai Israel had set them aside, still they were not given to Aaron and his sons until this day when the sanctuary was anointed.
