32 and that they should keep the duty of the Tent of Meeting, and the duty of the holy place, and the duty of the sons of Aaron their brothers, for the service of the house of Yahweh.

The charge of the sons of Aaron - It was the priests' business to kill, flay, and dress, as well as to offer, the victims, but being few, they were obliged to employ the Levites to flay those animals. The Levites were, properly speaking, servants to the priests, and were employed about the more servile part of Divine worship.
And that they should keep the charge of the tabernacle of the congregation,.... That no unclean persons entered into it, and that none of the vessels were carried out of it; this was the business of the porters:
and the charge of the holy place; of things that belonged unto it, the vessels in it, and what was requisite for it, and used there: and the charge of the sons of Aaron their brethren; the priests, whatever they should command them to do: in the service of the house of the Lord; in any part and branch of it before specified.
In conclusion, the whole duties of the Levites are summed up in three clauses: they were to keep the charge of the tabernacle, the charge of the sacred things, i.e., of all the sacred things of the worship, and the charge of the sons of Aaron, i.e., of all that the priests committed to them to be done; cf. Numbers 18:3., where these functions are more exactly fixed.
Charge - What the priests should commit to their charge, or command them to do.
