2 Chronicles 20:22

“And when they began to sing and to praise, etc.] 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,…”

“THE OVERTHROW OF HIS ENEMIES. (Ch2 20:22-30) when they began to sing and to praise the Lord set ambushments against the children of Ammon, Moab, and Mount Seir--Some think that this was done by angels in human form, whose sudden appearance diffused an uncontrollable panic. Others entertain the more probable opinion that, in the camp of this vast horde, composed of different tribes, jealousies and animosities had sprung up, which led to widespread dissensions and fierce feuds, in which they drew the sword against each other.

“To sing - So acceptable are the fervent prayers of God's people to God, and so terrible to their enemies.

Or, God raised jealousies and animosities among themselves, which broke forth, first into secret ambushments, which one party laid for another, and then into open hostilities to their utter destruction.

Jdg 7:22; Sa1 14:16, Sa1 14:20; Kg2 6:17; Psa 35:5, Psa 35:6; Isa 19:2; Eze 38:21 were smitten: or, smote one another 2 Chronicles 20:23”

“And at the time when they (having come into the neighbourhood of the hostile camp) began with singing and praising, Jahve directed liers in wait against the sons of Ammon, Moab, and Mount Seir, who were come against Judah, and they were smitten. מארבים denotes liers in wait, men hidden in ambush and lying in wait ( Jdg 9:25). Who are here meant cannot be ascertained with certainty.
