This verse in the King James

King James wording
And the Levites were purified, and they washed their clothes; and Aaron offered them as an offering before the LORD; and Aaron made an atonement for them to cleanse them.

The verse pairs covering with cleansing: Aaron’s act of covering brings the Levites into cleanness before the LORD.

Cleansing here reaches the whole person before the LORD: what is worn is washed, and the person is covered so they can be clean. Readiness is received through that cleansing, not claimed as a state untouched by need.

וַיְכַפֵּר

wayḵappēr

GROWS FROM

כפר

Cover; make a covering.

“covered for them” in this verse is wayḵappēr. The Hebrew verb translated “made an atonement” comes from kaphar, “cover.” The verse places that covering beside cleansing in the same action, so the covering is part of how the Levites are brought to cleanness.

ALSO GROWS

kappōret: Cover of the ark; often rendered “mercy seat.”

כַּפֹּרֶת

This is another form from ⁨כפר⁩, giving the root’s image of a covering a concrete place in the sanctuary.

kōfer: Covering price or ransom.

כֹּפֶר

This branch shows the root’s covering language can also describe a payment that answers a claim, adding depth to Aaron’s act on behalf of the Levites.

וַיִּתְחַטְּאוּ

wayyiṯḥaṭṭəʾû

GROWS FROM

חטא

Miss, err; the root associated with missing and sin.

“purified themselves of falling short” in this verse is wayyiṯḥaṭṭəʾû. The Hebrew verb for “were purified” is formed from the same root as ⁨חֵטְא⁩, “missing.” In this form, that root describes purification, linking cleanness with the addressing of what has gone wrong.

ALSO GROWS

ḥēṭʾ: Missing, error, sin.

חֵטְא

This familiar branch makes the link between purification and what needs to be addressed visible in the verse’s Hebrew.

ḥaṭṭāʾt: Sin; also a purification offering.

חַטָּאת

The same root can name both the missing and an offering associated with purification, echoing the verse’s movement from purification to offering and covering.

Across Scripture, purification is pictured as washing that makes a person clean before God.

And the LORD said to Moses, Go to the people, and set them apart today and tomorrow, and let them wash their clothes.
Exodus 19:10 · SDVWashing the clothes accompanies being set apart, as it does for the Levites here.
Remove my falling short with hyssop, and I am clean; tread me, and I am whiter than snow.
Psalm 51:7 · SDVThe verse joins washing with the inward cleanness the speaker seeks before God.
And I say to him, My lord, you know. And he says to me, These are the ones who come out of the great pressure, and they have washed their robes and made them white in the blood of the Lamb.
Revelation 7:14 · SDVWashed garments again make purification visible in the person’s approach before God.
For on that day the priest makes a covering for you, to cleanse you, so that you may be clean from all your shortcomings before the LORD.
Leviticus 16:30 · SDV

The Hebrew again places kaphar, “cover,” beside cleansing: the priest covers the people so they may be clean before the LORD. That pairing opens Numbers 8:21 further, where Aaron’s covering and the Levites’ purification belong to one movement.
