John Gill Commentary 2 Chronicles 20:27

"Then they returned, every man of Judah and Jerusalem, and Jehoshaphat in the forefront of them, to go again to Jerusalem with joy; for Jehovah had made them to rejoice over their enemies." — 2 Chronicles 20:27 (ASV)

Then they returned, every man of Judah and of Jerusalem, and
Jehoshaphat at the forefront of them, to go again to Jerusalem with
joy
There to praise the Lord in the temple, as they had done in the valley:

for the Lord had made them to rejoice over their enemies ;
by giving them a complete victory, and making them masters of so much wealth and riches.
