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 The Levites, of the children of the Kehati and of the children of the Korchi, stood up to praise the LORD, the God of Yisra'el, with an exceeding loud voice.

20 They rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Yehoshafat stood and said, Hear me, Yehudah, and you inhabitants of Yerushalayim: believe in the LORD your God, so shall you be established; believe his prophets, so shall you prosper.

21 When he had taken counsel with the people, he appointed those who should sing to the LORD, and give praise in holy array, as they went out before the army, and say, Give thanks to the LORD; for his lovingkindness endures forever.

22 When they began to sing and to praise, the LORD set liers-in-wait against the children of `Ammon, Mo'av, and Mount Se`ir, who had come against Yehudah; and they were struck.

23 For the children of `Ammon and Mo'av stood up against the inhabitants of Mount Se`ir, utterly to kill and destroy them: and when they had made an end of the inhabitants of Se`ir, everyone helped to destroy another.
