2 Chronicles 30:22 Commentary - English Annotations on the Holy Bible by Matthew Poole
Spake comfortably unto all the Levites; encouraged them to a cheerful and diligent attendance upon their holy ministrations by the promise of his favour and utmost care for them, which he faithfully performed, 2Ch 31:4, &c.
That taught the good knowledge of the Lord; who by their office were to instruct and build up the people in the knowledge and fear of God; which is mentioned as the cause of his respect and kindness to them, which was for their work’s sake, as it is said, 1Th 5:13.
Making confession: either,
1. Confessing their sins; which work was to accompany many of their sacrifices; of which see Lev 5:5; 16:21. Or rather,
2. Confessing God’s goodness, or praising of God, which oft goes under this name, as 1Ch 16:8,24, which also seems to be more proper work for this season of joy.

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.
