16 He said, “Thus says Yahweh, ‘Make this valley full of trenches.’ 17 For thus says Yahweh, ‘You will not see wind, neither will you see rain; yet that valley shall be filled with water, and you will drink, both you and your livestock and your animals. 18 This is but a light thing in the sight of Yahweh. He will also deliver the Moabites into your hand. 19 You shall strike every fortified city, and every choice city, and shall fell every good tree, and stop all springs of water, and mar every good piece of land with stones.’”
20 It happened in the morning, about the time of offering the offering, that behold, water came by the way of Edom, and the country was filled with water. 21 Now when all the Moabites heard that the kings had come up to fight against them, they gathered themselves together, all who were able to put on armor, and upward, and stood on the border. 22 They rose up early in the morning, and the sun shone on the water, and the Moabites saw the water over against them as red as blood. 23 They said, “This is blood. The kings are surely destroyed, and they have struck each other. Now therefore, Moab, to the spoil!” 24 When they came to the camp of Israel, the Israelites rose up and struck the Moabites, so that they fled before them; and they went forward into the land smiting the Moabites. 25 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 springs of water, and felled all the good trees, until in Kir Hareseth only they left its stones; however the men armed with slings went about it, and struck it.

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.
