2 Chronicles 30:17 Commentary - English Annotations on the Holy Bible by Matthew Poole
That were not sanctified; that had more desire to come to the passover, than care and diligence to cleanse and prepare themselves for it. Now these persons were either,
1. The priests, who were before taxed with uncleanness and unpreparedness. Or rather,
2. The people, as is implied in the word
congregation, and expressed in the next verse, and confirmed by the reason here following.
The Levites had the charge of the killing, because many of the people were unclean, and therefore many more sacrifices were to be offered for their purification than the priests could kill. Of the passovers, i.e. either,
1. The paschal lambs: which the Levites here offered, because of the impurity of many of the masters of families, who otherwise, as some think, should have killed the paschal lambs in their own houses, Exo 12:3. Or,
2. The other sacrifices which accompanied the passover, which also are called by the same name, as is evident from Deu 16:2,3, where See Poole "Deu 16:2", See Poole "Deu 16:3"; which the Levites here killed for the reason now mentioned.
For every one that was not clean; so far as they could make any discovery of their uncleanness, either by their own confession, or otherwise. But there were many whose uncleannesses were not known, and therefore did not cleanse themselves, as is said, 2Ch 30:18, as they ought to have done.

English Annotations on the Holy Bible by Matthew Poole
Matthew Poole (1624–1679) wrote English Annotations on the Holy Bible, completing the chapters as far as Isaiah 58 before his death in 1679. The rest of the Annotations were completed by friends and colleagues among his Nonconformist brethren. The first printing of the completed edition was in 1685, 2 volumes folio, followed by editions in 1688, 1696 (with valuable chapter outlines added by the editors, Samuel Clark and Edward Veale), and the 4th and definitive edition in 1700, the basis of all others.
