16 He then said, "God's word: Dig ditches all over this valley. 17 Here's what will happen - you won't hear the wind, you won't see the rain, but this valley is going to fill up with water and your army and your animals will drink their fill. 18 This is easy for God to do; he will also hand over Moab to you. 19 You will ravage the country: Knock out its fortifications, level the key villages, clear-cut the orchards, clog the springs, and litter the cultivated fields with stones."
20 In the morning - it was at the hour of morning sacrifice - the water had arrived, water pouring in from the west, from Edom, a flash-flood filling the valley 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.
