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 They got up early in the morning and went to the desert of Tekoa. As they were leaving, Jehoshaphat stopped and said, "Listen to me, people of Judah and those living in Jerusalem. Trust the LORD your God, and believe. Believe his prophets, and you will succeed."

21 After he had advised the people, he appointed people to sing to the LORD and praise him for the beauty of his holiness. As they went in front of the troops, they sang, "Thank the LORD because his mercy endures forever!"

22 As they started to sing praises, the LORD set ambushes against the Ammonites, Moabites, and the people of Mount Seir who had come into Judah. They were defeated.

23 Then the Ammonites and Moabites attacked the people from Mount Seir and annihilated them. After they had finished off the people of Seir, they helped destroy one another.

24 The people of Judah went to the watchtower in the desert and looked for the crowd. Corpses were lying on the ground. No one had escaped.
