And thou shalt gird them with girdles (Aaron and his sons),
&c.] Aaron with the girdle of the ephod, and with the girdle of needlework, and his sons with common girdles made for them; all which showed what strength, diligence, and expedition were necessary for the discharge of their office:
and the priest's office shall be theirs for a perpetual statute;
that is, shall descend from father to son in Aaron's family throughout all generations, until the Messiah should come; who would be a priest of another order, and put an end to the Aaronic priesthood, by fulfilling what that was a type of, and so abolishing it:
and thou shall consecrate Aaron and his sons;
or "fill the hand of them"; that is, with sacrifices to offer for themselves and others, (See Gill on Exodus 28:41). The Targums of Onkelos and Jonathan are,
``shall offer the offering of Aaron, and the offering of his sons,''of which there is an after account, and was one part of their consecration.
