2 Kings 3:23

23 "It's blood!" they exclaimed. "The three enemy armies must have fought and killed each other! Let's go and loot their camp!"

2 Kings 3:23 Meaning and Commentary

2 Kings 3:23

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.

2 Kings 3:23 In-Context

21 When the Moabites heard that the three kings had come to attack them, all the men who could bear arms, from the oldest to the youngest, were called out and stationed at the border.
22 When they got up the following morning, the sun was shining on the water, making it look as red as blood.
23 "It's blood!" they exclaimed. "The three enemy armies must have fought and killed each other! Let's go and loot their camp!"
24 But when they reached the camp, the Israelites attacked them and drove them back. The Israelites kept up the pursuit, slaughtering the Moabites
25 and destroying their cities. As they passed by a fertile field, every Israelite would throw a stone on it until finally all the fields were covered; they also stopped up the springs and cut down the fruit trees. At last only the capital city of Kir Heres was left, and the slingers surrounded it and attacked it.
