2 Chronicles 20:22 Meaning and Commentary

2 Chronicles 20:22

And when they began to sing and to praise
They sung more or less all the way they went, from the time they set out, but when they came nearer the enemy, they sung louder and louder: the Lord set ambushments against the children of Ammon, Moab, and Mount
Seir, which came against Judah;
some take them to be their own ambushments, which they set for the destruction of Judah; but the Lord turned them against their own confederates, mistaking them for Jews; so the Vulgate Latin version,

``the Lord turned their ambushments against themselves;''

or rather these were angels, who appeared in the form of the Edomites, and so fell upon the Ammonites and Moabites: and they were smitten;
by them, many of them were destroyed; hence it follows,

2 Chronicles 20:22 In-Context

20 In the morning they got up early and went out to the wilderness of Tekoa. As they were about to go out, Jehoshaphat stood and said, "Hear me, Judah and you inhabitants of Jerusalem. Believe in the Lord your God, and you will be established; believe in His prophets, and you will succeed."

21 Then he consulted with the people and appointed some to sing for the Lord and some to praise the splendor of [His] holiness. When they went out in front of the armed forces, they kept singing: Give thanks to the Lord, for His faithful love endures forever.

22 The moment they began [their] shouts and praises, the Lord set an ambush against the Ammonites, Moabites, and [the inhabitants of] Mount Seir who came [to fight] against Judah, and they were defeated.

23 The Ammonites and Moabites turned against the inhabitants of Mount Seir and completely annihilated them. When they had finished with the inhabitants of Seir, they helped destroy each other.

24 When Judah came to a place overlooking the wilderness, they looked toward the multitude, and there were corpses lying on the ground; nobody had escaped.
