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.
