21 The Levites purified themselves from sin, and they washed their clothes; and Aaron offered them for a wave offering before Yahweh; and Aaron made atonement for them to cleanse them.

And the Levites were purified, and they washed their clothes We have already spoken of the washing, for since it was required of all private individuals, much less would it be allowable for the Levites to handle the sacred things, unless they were first purified. But what follows as to their presentation by the hands of Aaron, was a shadowing forth by symbol of the truth, which at length shone out at the coming of Christ; for it had been of old predicted by the Prophets, that, in the renovation of the Church, those who had hitherto been but of the multitude should become Levites. Therefore, by this figure, God would declare that none even of His elect servants would be approved of and accepted by Him, unless sanctified by the one Priest. And thence an atonement is joined with their offering, in order that the Levites might be pure.
Were purified - Rather, purified themselves; as directed in Numbers 8:7.
And Aaron made an atonement for them - Though the Levites had been most solemnly consecrated to the Lord's service, and though all legal washings and purifications were duly performed on the occasion, yet they could not approach God till an atonement had been made for them. How strange is it, after all these significations, of the will and purpose of God relative to man, that any priest or any people will attempt to draw nigh to God without an atonement! As sure as God hath spoken it, there is no entrance into the holiest but through the blood of Jesus, Hebrews 10:19, Hebrews 10:20.
And the Levites were purified,.... From sin, by the sprinkling of the sin water, or water of purification on them, Numbers 8:7,
and they washed their clothes; that they might have no defilement about them, neither in their bodies, nor in their garments:
and Aaron offered them as an offering before the Lord; a wave offering, as in Numbers 8:11,
and Aaron made an atonement for them to cleanse them; by offering the sacrifices for them, Numbers 8:12.
