Here is, I. The general character of Amaziah: He did that which was right in the eyes of the Lord, worshipped the true God, kept the temple service a going, and countenanced religion in his kingdom; but he did not do it with a perfect heart (Ch2 25:2), that is, he was not a man of serious piety or devotion himself, nor had he any zeal for the exercises of religion. He was no enemy to it, but a cool and indifferent friend. Such is the character of too many in this Laodicean age: they do that which is good, but not with the heart, not with a perfect heart.

II.A necessary piece of justice which he did upon the traitors that murdered his father: he put them to death, Ch2 25:3. Though we should suppose they intended to avenge on their king the death of the prophet (as was intimated, Ch2 24:25), yet this would by no means justify their wickedness; for they were not the avengers, but presumptuously took God's work out of his hands: and therefore Amaziah did what became him in calling them to an account for it, but forbade the putting of the children to death for the parents' sin, Ch2 25:4.

III.An expedition of his against the Edomites, who, some time ago, had revolted from under the dominion of Judah, to which he attempted to reduce them. Observe,

1.The great preparation he made for this expedition. (1.) He mustered his own forces, and marshalled them (Ch2 25:5), and found Judah and Benjamin in all but 300,000 men that were fit for war, whereas, in Jehoshaphat's time, fifty or sixty years before, they were four times as many. Sin weakens a people, diminishes them, dispirits them, and lessens their number and figure. (2.) He hired auxiliary troops out of the kingdom of Israel, Ch2 25:6. Finding his own kingdom defective in men, he thought to make up the deficiency with his money, and therefore took into his pay 100,000 Israelites. If he had advised with any of his prophets before he did this, or had but considered how little any of his ancestors got by their alliances with Israel, he would not have had this to undo again. But rashness makes work for repentance.

2.The command which God sent him by a prophet to dismiss out of his service the forces of Israel, Ch2 25:7, Ch2 25:8. He would not have him call in any assistance at all: it looked like distrust of God. If he made sure of God's presence, the army he had of his own was sufficient. But particularly he must not take in their assistance: For the Lord is not with the children of Ephraim, because they are not with him, but worship the calves. This was a good reason why he should not make use of them, because he could not depend upon them to do him any service. What good could be expected from those that had not God with them, nor his blessings upon their undertakings? It is comfortable to employ those who, we have reason to hope, have an interest in heaven, and dangerous to associate with those from whom the Lord has departed. The prophet assured him that if he persisted in his resolution to take these idolatrous apostate Israelites with him, in hopes thereby to make himself strong for the battle, it was at his peril; they would prove a dead weight to his army, would sink and betray it: "God shall make thee fall before the enemy, and these Israelites will be the ruin of thy cause; for God has power to help thee without them, and to cast thee down though thou hast them with thee."

3.The objection which Amaziah made against this command, and the satisfactory answer which the prophet gave to that objection, Ch2 25:9. The king had remitted 100 talents to the men of Israel for advance-money. "Now," says he, "if I send them back, I shall lose that: But what shall we do for the 100 talents?" This is an objection men often make against their duty: they are afraid of losing by it. "Regard not that," says the prophet: "The Lord is able to give thee much more than this; and, thou mayest depend upon it, he will not see thee lose by him. What are 100 talents between thee and him? He has ways enough to make up the loss to thee; it is below thee to speak of it." Note, A firm belief of God's all-sufficiency to bear us out in our duty, and to make up all the loss and damage we sustain in his service abundantly to our advantage, will make his yoke very easy and his burden very light. What is it to trust in God, but to be willing to venture the loss of any thing for him, in confidence of the goodness of the security he gives us that we shall not lose by him, but that whatever we part with for his sake shall be made up to us in kind or kindness. When we grudge to part with any thing for God and our religion, this should satisfy us, that God is able to give us much more than this. He is just, and he is good, and he is solvent. The king lost 100 talents by his obedience; and we find just that sum given to his grandson Jotham as a present (Ch2 27:5); then the principal was repaid, and, for interest, 10,000 measures of wheat and as many of barley.

4.His obedience to the command of God, which is upon record to his honour. He would rather lose his money, disoblige his allies, and dismiss a fourth part of his army just as they were going to take the field, than offend God: He separated the army of Ephraim, to go home again, Ch2 25:10. And they went home in great anger, taking it as a great affront thus to be made fools of, and to be cashiered as men not fit to be employed, and being perhaps disappointed of the advantages they promised themselves in spoil and plunder by joining with Judah against Edom. Men are apt to resent that which touches them in their profit or reputation, though it frees them from trouble.

5.His triumphs over the Edomites, Ch2 25:11, Ch2 25:12. He left dead upon the spot, in the field of battle, 10,000 men; 10,000 more he took prisoners, and barbarously killed them all by throwing them down some steep and craggy precipice. What provocation he had to exercise this cruelty towards them we are not told; but it was certainly very severe.

6.The mischief which the disbanded soldiers of Israel did to the cities of Judah, either in their return or soon after, Ch2 25:13. They were so enraged at being sent home that, if they might not go to share with Judah in the spoil of Edom, they would make a prey of Judah. Several cities that lay upon the borders they plundered, killing 3000 men that made resistance. But why should God suffer this to be done? Was it not in obedience to him that they were sent home, and yet shall the country thus suffer by it? Surely God's way is in the sea! Did not the prophet say that God was not with the children of Ephraim, and yet they are suffered to prevail against Judah? Doubtless God intended hereby to chastise those cities of Judah for their idolatries, which were found most in those parts that lay next to Israel. The men of Israel had corrupted them, and now they were made a plague to them. Satan both tempts and torments.

They returned home in great anger - They thought they were insulted, and began to meditate revenge. See the notes on 2 Kings 14:1-20 (note), where almost every circumstance in this chapter is examined and explained.

And other ten thousand left alive did the children of Judah carry away captive,.... The rest of the army of the Edomites, which amounted to the same number, fell into their hands, and they took them, and carried them off:

and brought them unto the top of the rock; very probably the same on which the city Petra, the metropolis of Edom, was built, called also Selah, Kg2 14:7 both which names signify a rock. Josephus (g) calls it the great rock in Arabia; that is, Arabia Petraea:

and cast them down from the top of the rock, that they were broken all in pieces; burst asunder, bones broken, and limb from limb separated. This sort of punishment was inflicted by the Romans on various malefactors, by casting them down from the Tarpeian rock (h); and in Greece, according to the Delphian law, such as were guilty of sacrilege were led to a rock, and cast down headlong from thence (i): and now in Turkey, at a place called Constantine, a town situated on the top of a great rock, the usual way of executing great criminals is by pushing them from off the cliff (k); see Luk 4:29, but to use captives taken in war after this manner seems cruel and barbarous; and what should be the reason of such treatment of them is not easy to say.

valley of salt--This ravine lies to the south of the Dead Sea. The arms of Amaziah, in reward for his obedience to the divine will, were crowned with victory--ten thousand of the Edomites were slain on the field, and as many taken prisoners, who were put to death by precipitation "from the top of the rock" [Ch2 25:12]. This rock might be situated in the neighborhood of the battlefield, but more probably it formed one of the high craggy cliffs of Selah (Petra), the capital of the Edomites, whither Amaziah marched directly from the Valley of Salt, and which he captured (Kg2 14:7). The savage cruelty dealt out to them was either in retaliation for similar barbarities inflicted on the Hebrews, or to strike terror into so rebellious a people for the future. The mode of execution, by dashing against stones (Psa 137:9), was common among many ancient nations.
