Matthew Henry Presbyterian @wholebiblehenry

We have here the foregoing prayer answered and the foregoing promise performed, in the total overthrow of the enemies' forces and the triumph (for so it was rather than a victory) of Jehoshaphat's forces over them. I. Never was army drawn out to the field of battle as Jehoshaphat's was.

So the realm of Jehoshaphat was quiet,.... Both within and without; they were at peace among themselves, and none from abroad dared to molest them: for his God gave him rest round about; from all his enemies; the Targum has it, the Word of his God; and so, in the preceding verse, the Word of the Lord fought; and in Ch2 20:28 the Word of the Lord made them rejoice.

2Ch 20:29-30 The fame of this victory of the Lord over the enemies of Israel caused the terror of God to be spread abroad over all the kingdoms of the surrounding lands, in consequence of which the kingdom of Judah had rest (cf. 2Ch 17:10). On the last clause of 2Ch 20:30, cf. 2Ch 15:15.
