2 Chronicles 24:6 Commentary - English Annotations on the Holy Bible by Matthew Poole
Jehoiada the chief: it is observable, that he is not called the chief priest, or high priest, but only
the chief, or &c the head, which he might be in many other respects, either by reason of his near relation to the royal family; or because he was the chief of one of the twenty-four families; or because he had been the chief man in the contriving and bringing about of this great change, and the general of the forces employed about it. And the high priest seems to be mentioned as a distinct person from Jehoiada here, 2Ki 12:9,10; all which make it questionable whether Jehoiada was the high priest or no.
The collection, according to the commandment of Moses, Heb. the collection of Moses, i.e. such a one as he commanded or made in the like case; of which See Poole "2Ch 24:5". In like manner we read of the sins of Manasseh, 2Ki 24:3, and of the sin of Jeroboam frequently.

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.
