25 The cities they overturned, and on every good piece of land everyone threw a stone, until it was covered; every spring of water they stopped up, and every good tree they felled. Only at Kir-hareseth did the stone walls remain, until the slingers surrounded and attacked it. 26 When the king of Moab saw that the battle was going against him, he took with him seven hundred swordsmen to break through, opposite the king of Edom; but they could not. 27 Then he took his firstborn son who was to succeed him, and offered him as a burnt offering on the wall. And great wrath came upon Israel, so they withdrew 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.
