2 Chronicles 20:22

22. The Lord set ambushments against… Ammon, Moab… mount Seir The word rendered ambushments is מארבים , liers in wait. Compare Judges 9:29. A measure of uncertainty must ever rest upon the question, Who were these liers in wait? They were not men of Judah, for these were not to fight. 2 Chronicles 20:15; 2 Chronicles 20:17. Nor were they portions of the invading army, who, by mistake, fell to fighting one another, for such could not be properly called liers in wait. Many expositors, ancient and modern, think that they were angels sent by God to confuse and overthrow the enemies of his people. But it would be very strange for the sacred writer to call angels “liers in wait.” Had he meant angels he would most likely have said so. More probably the ambush was composed of a band of daring marauders, not belonging to either army, who, greedy for spoil, attacked the combined army unexpectedly and with such fury as to put them all in confusion, and “every man’s sword was turned against his fellow.” Compare Judges 7:22, and 1 Samuel 14:20. Perhaps these marauders themselves perished in the general fray. In all this the sacred writer saw the hand of Jehovah.
