2 Chronicles 25:13 Commentary - English Annotations on the Holy Bible by Matthew Poole
Unto Beth-horon, to wit, Beth-horon the lower, which was in the tribe of Benjamin; and from thence to Samaria; either,
1. To the city of Samaria; for the kings of Judah had taken divers places within the kingdom of Israel. Or,
2. To the kingdom of Samaria; Beth-horon and all other places between that city and their own kingdom.
Smote, i.e. killed, as that word is generally understood.
Three thousand of them; not three thousand cities, but three thousand persons dwelling in them, who possibly opposed them in taking the spoil, which was the thing they sought.

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.
