2 Chronicles 17:11 Commentary - English Annotations on the Holy Bible by Matthew Poole
Some of the Philistines; who had been subjects to this kingdom ever since David’s time, but, it seems, had neglected this duty in the times of his predecessors, but now were moved by their own fears to perform it.
The Arabians brought him flocks; either because he had upon some just occasion waged war against them, and subdued them, though the particulars of it be not described in Scripture; or because they voluntarily put themselves under his protection, in recompence whereof they sent him those presents; or only as a free acknowledgment of their respects to him.

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.
