20 In the morning - it was at the hour of morning sacrifice - the water had arrived, water pouring in from the west, from Edom, a flash-flood filling the valley with water. 21 By this time everyone in Moab had heard that the kings had come up to make war against them. Everyone who was able to handle a sword was called into service and took a stand at the border. 22 They were up and ready early in the morning when the sun rose over the water. From where the Moabites stood, the water reflecting the sun looked red, like blood. 23 "Blood! Look at the blood!" they said. "The kings must have fought each other - a bloody massacre! Go for the loot, Moab!" 24 When Moab entered the camp of Israel, the Israelites were up on their feet killing Moabites right and left, the Moabites running for their lives, Israelites relentless in pursuit - a slaughter. 25 They leveled the towns, littered the cultivated fields with rocks, clogged the springs, and clear-cut the orchards. Only the capital, Kir Hareseth, was left intact, and that not for long; it too was surrounded and attacked with thrown and flung rocks. 26 When the king of Moab realized that he was fighting a losing battle, he took seven hundred swordsmen to hack a corridor past the king of Edom, but they didn't make it. 27 Then he took his son, his firstborn who would succeed him as king, and sacrificed him on the city wall. That set off furious anger against Israel. Israel pulled back and returned home.

Commentary on 2 Kings 3:20-27
(Read 2 Kings 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.
