Charles Ellicott Commentary 2 Chronicles 20:30

"So the realm of Jehoshaphat was quiet; for his God gave him rest round about." — 2 Chronicles 20:30 (ASV)

So the realm of Jehoshaphat. —The same is said of Asa’s kingdom (2 Chronicles 14:5–6; 2 Chronicles 15:15). (Compare the similar notices in Judges of the rest which followed upon the overthrow of a national enemy, e.g.,Judges 3:30.)
