20 Moses, and Aaron, and all the congregation of the children of Israel did so to the Levites. According to all that Yahweh commanded Moses concerning the Levites, so the children of Israel did to them.

And Moses, and Aaron, and all the congregation The Levites also are now inaugurated for the performance of their duties, but in their proper order, because their condition was inferior. Here it must be noted that the sons of Moses and their descendants were placed in this lower rank, and excluded from all expectation of the priesthood. Hence the ingratitude of the whole people, and especially of the tribe of Levi, was all the more base, when they presumptuously sought the honor from which Moses had shut out his children for ever. It was then no ordinary act of obedience in him to execute what God had appointed respecting the Levites. Aaron is here mentioned, because he consecrated the Levites in right of his priesthood. As regards the people, their consent is merely commended, because they agreed to what was the pleasure of God. But this virtue in them only increased their ignominy afterwards, when they sought to overthrow that divine decree of which they had approved.
And Moses and Aaron, and all the congregation of the children of Israel,.... The several parties concerned in the consecration of the Levites: these
did to the Levites according unto all that the Lord commanded Moses,
so did the children of Israel unto them: which, as Jarchi notes, is said to the praise of them that did it, and of what was done by them; everything was done that was ordered, and in the manner in which it was prescribed; Moses sprinkled, or ordered to be sprinkled, the water of purification on them, and set them before the tabernacle, and before the Lord; the children of Israel laid their hands on them, and Aaron waved them, offered the sacrifices for them.
Numbers 8:20-22 contain an account of the execution of the divine command.
