2 Chronicles 26:21 Commentary - English Annotations on the Holy Bible by Matthew Poole
Unto the day of his death: God would have this leprosy to be incurable, as a lasting monument of his anger against such presumptuous invaders of the priest’s office.
Dwelt in a several house; as he was obliged to do by law, Lev 13:16, which he durst not now resist, being under the hand and stroke of God, and under the fear of further and worse plagues, if he did so.
For he was cut off; so the following words are a reason of the former; he dwelt in a several house, because he might not come into the temple or courts, nor consequently into any public assembly, or the society of others. Or, and therefore, as the Hebrew chi often signifies; and the particle and is oft understood. So it is an inference from the next foregoing words, He was a leper, and therefore he was cut off, &c. He who could not content himself with God’s allowance, but usurped the priest’s place and office, is now deprived of the privilege of the meanest of his people. A just and most suitable judgment.

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.
