And thou shalt set the Levites before Aaron, and before his
sons
After atonement was made for them, as Aben Ezra observes; then they were presented to Aaron and his sons, to whom they were given to he their ministers, and assistants to them:
and offer them [for] an offering unto the Lord:
or, and "waved them", &c. as before, that is, order them to be waved; for not Moses, but Aaron, did this, and indeed was done already; and therefore should rather be rendered, as by Bishop Patrick, after thou hast offered, or waved them.
