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;''

2 Chronicles 20:22 In-Context

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!

24 When Judah arrived at the point overlooking the wilderness, all they could see were corpses lying all over the ground. There were no survivors.
