(23) The kings are surely slain.--Have surely fought with (or destroyed) one another. LXX., ??????????. The supposition was not improbable. Confederates of different races not seldom had been known to fall out among themselves (comp. Judges 7:22; 2Chronicles 20:23, and Note), and in this case the old enmity of Edom towards Israel, and the suppressed jealousies between Israel and Judah, made such a result very likely. The Moabites would know also that the wady had been waterless, so that their mistake was natural. When once their instinct for plunder was aroused they did not stop to think, but with a wild cry of "Moab, to the spoil !" they rushed in disorder upon the Israelite camp.

Verse 23. - And they said, This is blood. Even Ewald recognizes here "a historical background for the narrative." The idea of such a mistake could scarcely have occurred to a romancer. The kings are surely slain, and they have smitten one another. There were rivalries and jealousies subsisting between Judah, Israel, and Edom, which made it quite possible that at any time open quarrel might break out among them. Edom especially was, it is probable, a reluctant member of the confederacy, forced to take her part in it by her suzerain, Jehoshaphat. The Moabites, moreover, had recently had personal experience how easily the swords of confederates might be turned against each other, since their last expedition against Judah (2 Chronicles 20:1-25) had completely failed through such a sudden disagreement and contention. Now therefore, Moab, to the spoil. If their supposition were correct, and the kings had come to blows, and the hosts destroyed each other, Moab would have nothing to do but to fly upon the spoil, to strip the slain, and plunder the camp of the confederates. A disorderly rush took place for this purpose (see Josephus, 'Ant. Jud.,' 9:3. § 2).

3:20-27 It is a blessing to be favoured with the company of those who have power with God, and can prevail by their prayers. A kingdom may be upheld and prosper, in consequence of the fervent prayers of those who are dear to God. May we place our highest regard upon such as are most precious in his account. When sinners are saying Peace, peace, destruction comes upon them: despair will follow their mad presumption. In Satan's service and at his suggestion, such horrid deeds have been done, as cause the natural feelings of the heart to shudder; like the king of Moab's sacrificing his son. It is well not to urge the worst of men to extremities; we should rather leave them to the judgment of God.And they said, this is blood,.... They were very confident of it, having no notion of water, there having been no rain for some time; and perhaps it was not usual to see water at any time in this place:

the kings are surely slain; they and their forces:

and they have smitten one another; having quarrelled either about their religion, or about want of water, and the distress they were come into through it, laying the blame of their coming out to war, or of their coming that way, on one another; and the Moabites might rather think something of this kind had happened, from what had lately been done among themselves, and their allies, 2 Chronicles 20:23.

now therefore, Moab, to the spoil; having no occasion to fight, or prepare for it; all they had to do was to march directly to the enemy's camp, and plunder it.
