20 It happened in the morning, about the time of offering the offering, that behold, water came by the way of Edom, and the country was filled with water. 21 Now when all the Moabites heard that the kings had come up to fight against them, they gathered themselves together, all who were able to put on armor, and upward, and stood on the border. 22 They rose up early in the morning, and the sun shone on the water, and the Moabites saw the water over against them as red as blood. 23 They said, “This is blood. The kings are surely destroyed, and they have struck each other. Now therefore, Moab, to the spoil!” 24 When they came to the camp of Israel, the Israelites rose up and struck the Moabites, so that they fled before them; and they went forward into the land smiting the Moabites. 25 They beat down the cities; and on every good piece of land they cast every man his stone, and filled it; and they stopped all the springs of water, and felled all the good trees, until in Kir Hareseth only they left its stones; however the men armed with slings went about it, and struck it. 26 When the king of Moab saw that the battle was too severe for him, he took with him seven hundred men who drew sword, to break through to the king of Edom; but they could not. 27 Then he took his eldest son who would have reigned in his place, and offered him for a burnt offering on the wall. There was great wrath against Israel: and they departed from him, and returned to their own land.

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.
