16 And he said, "Thus says the Lord, "I will make this wadi full of pools.' 17 For thus says the Lord, "You shall see neither wind nor rain, but the wadi shall be filled with water, so that you shall drink, you, your cattle, and your animals.' 18 This is only a trifle in the sight of the Lord, for he will also hand Moab over to you. 19 You shall conquer every fortified city and every choice city; every good tree you shall fell, all springs of water you shall stop up, and every good piece of land you shall ruin with stones."
20 The next day, about the time of the morning offering, suddenly water began to flow from the direction of Edom, until the country was filled with water.

Commentary on 2 Kings 3:6-19
(Read 2 Kings 3:6-19)
The king of Israel laments their distress, and the danger they were in. He called these kings together, yet he charges it upon Providence. Thus the foolishness of man perverteth his way, and then his heart fretteth against the Lord, Psalm 84:6. We need not inquire whence the water came. God is not tied to second causes. They that sincerely seek for the dew of God's grace, shall have it, and by it be made more than conquerors.
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.
