Ellicott's Commentary On The Whole Bible
2 Chronicles 20 - Introduction
XX.
INVASION OF THE MOABITES, AMMONITES, AND MAONITES. THEIR MARVELLOUS OVERTHROW — (2 Chronicles 20:1).
The chronicler only has preserved an historic account of this great deliverance. But certain of the Psalms have been with much probability supposed to commemorate it. The contents of Psalms 46-48 harmonise well with this assumption; and they are referred by their titles to “the sons of Korah,” a fact which corresponds with the statement of 2 Chronicles 20:19 that certain of the Korahite Levites sang praises to Jehovah on occasion of the prophecy of Jahaziel. Further, Jahaziel himself was an Asaphite Levite, and it is noteworthy that Psalms 83, which is a prayer against a hostile confederacy of Edom, Amnion, Moab, and other races, is headed “A Psalm of Asaph.” It may have been composed by the prophet whose name is only recorded in this chapter.
