Matthew Henry Presbyterian @wholebiblehenry

Here is, I. The law concerning the consecration of Aaron and his sons to the priest's office, which was to be done with a great deal of ceremony and solemnity, that they themselves might be duly affected with the greatness of the work to which they were called, and that the people also might learn to magnify the office and none might dare to invade it. 1.

Commenting on Exodus 29:1-37

John Gill Reformed Baptist @doctorgill

And thou shalt put all in the hands of Aaron, and in the hands of his sons,.... Which accounts for the use of the phrase, filling the hand for consecration, Exo 29:9 for all the above things of the ram, bread, cakes, and wafers, were put into their hands when consecrated, denoting their investiture with their office: all things are in the hands of Christ...

For a wave-offering - See Clarke's note on Lev 7:1 etc., where an ample account of all the offerings, sacrifices, etc., under the Mosaic dispensation, and the reference they bore to the great sacrifice offered by Christ, is given in detail.
