25 And 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 fountains of water, and felled all the good trees, until in Kir-hareseth [only] they left the stones thereof; howbeit the slingers went about it, and smote it. 26 And when the king of Moab saw that the battle was too sore for him, he took with him seven hundred men that drew sword, to break through unto the king of Edom; but they could not. 27 Then he took his eldest son that should have reigned in his stead, and offered him for a burnt-offering upon the wall. And 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.
