2 Chronicles 20:22 Commentary - English Annotations on the Holy Bible by Matthew Poole
When they began to sing and to praise; so acceptable are the fervent prayers of God’s people to God, and so terrible to their enemies.
Ambushments, or, liers in wait; either,
1. The holy angels, who appeared in the shape of men, and possibly put on the appearances and visages of Moabites or Ammonites, and in that shape slew the rest, who supposing this slaughter to be done by a part of their own army, fell upon them, and so broke forth into mutual slaughters. Or,
2. God raised jealousies and animosities amongst themselves, which by degrees broke forth first into secret ambushments, which one party laid for another, and then into open hostilities and outrages to their utter destruction. So vain are all men’s attempts against God, who needs none to destroy his enemies but themselves, and their own mistakes and passions, which he can when he pleaseth arm against them.

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.
