2 Chronicles 30:27 Commentary - English Annotations on the Holy Bible by Matthew Poole
The priests the Levites; those of the Levites who were priests also; for to them only this work belonged, 1Ch 23:13. Or, the priests and the Levites; for as the Levites did some other part of the priests’ work at this time, it is not strange if they did this also. Or the priests might bless by solemn pronunciation of the blessing, and the Levites by their acclamations, or with their musical instruments.
Blessed the people; either commended them for their great zeal and diligence in God’s service; or rather, solemnly prayed to God to bless them; and their prayer was not in vain, as the following words show.

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.
