The sun had risen with a ruddy light, as is frequently the case after a storm (compare Matthew 16:3), nearly over the Israelite camp, and the pits, deep but with small mouths, gleaming redly through the haze which would lie along the newly moistened valley, seemed to the Moabites like pools of blood. The preceding year, they and their allies had mutually destroyed each other 2 Chronicles 20:23. It seemed to them, from their knowledge of the jealousies between Judah, Israel, and Edom, not unlikely that a similar calamity had now befallen their foes.

Therefore, Moab, to the spoil - Thus they came on in a disorderly manner, and fell an easy prey to their enemies.

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.

And they said, {o} This is blood: the kings are surely slain, and they have smitten one another: now therefore, Moab, to the spoil.

(o) The sudden joy of the wicked is but a preparation for their destruction, which is at hand.

slain: Heb. destroyed

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.
