2 Chronicles 20:21 Meaning and Commentary

2 Chronicles 20:21

And when he had consulted with the people
His principal officers, in what order they should march, and in what manner they should form themselves, when they met the enemy, and how they should conduct as if they were to engage: he appointed singers unto the Lord;
to sing his praise, and give him glory, as if the victory was already completed, it being so sure: and that should praise the beauty of holiness, as they went out before
the army;
that is, praise God, who is glorious in holiness, whose beauty lies in his holiness, and who is holy in all his ways and works: and to say, praise the Lord, for his mercy endureth for ever;
with which they were to conclude their songs of praise, as David did, and whose songs they might sing; see ( Psalms 136:1-26 ) .

2 Chronicles 20:21 In-Context

19 Levites from the lines of Kohath and Korah stood up to loudly praise the LORD, the God of Israel.

20 Early the next morning they went into the Tekoa wilderness. When they were about to go out, Jehoshaphat stood and said, "Listen to me, Judah and every inhabitant of Jerusalem! Trust the LORD your God, and you will stand firm; trust his prophets and succeed!"

21 After consulting with the people, Jehoshaphat appointed musicians to play for the LORD, praising his majestic holiness. They were to march out before the warriors, saying, "Give thanks to the LORD because his faithful love lasts forever!"

22 As they broke into joyful song and praise, the LORD launched a surprise attack against the Ammonites, the Moabites, and those from Mount Seir who were invading Judah, so that they were defeated.

23 The Ammonites and the Moabites turned on those from Mount Seir, completely destroying them. Once they had finished off the inhabitants of Seir, they helped to destroy each other!
