Leviticus 9:1

IX.

(1) And it came to pass on the eighth day. — That is, the day following the seven days of consecration. (See Leviticus 8:33) According to ancient tradition this was the first of the month Nisan, or March.

Moses called Aaron and his sons, and the elders. — That is, the same elders, the representatives of the people, who were called to attest the imposing ceremony of consecration (see Leviticus 8:3), are now also summoned to witness how the newly-installed priests entered upon the active duties of their ministrations. Like newly-born children who remain seven days in a state of uncleanness and enter into the covenant privileges of the congregation on the eighth day (see Leviticus 12:2), so the newly-created priests after a purging of seven days commenced their sacred duties and partook of their privileges on this symbolical day.
