6 He also hired a hundred thousand fighting men from Israel for a hundred talents[1] of silver. 7 But a man of God came to him and said, "Your Majesty, these troops from Israel must not march with you, for the Lord is not with Israel-not with any of the people of Ephraim. 8 Even if you go and fight courageously in battle, God will overthrow you before the enemy, for God has the power to help or to overthrow." 9 Amaziah asked the man of God, "But what about the hundred talents I paid for these Israelite troops?" The man of God replied, "The Lord can give you much more than that." 10 So Amaziah dismissed the troops who had come to him from Ephraim and sent them home. They were furious with Judah and left for home in a great rage. 11 Amaziah then marshaled his strength and led his army to the Valley of Salt, where he killed ten thousand men of Seir. 12 The army of Judah also captured ten thousand men alive, took them to the top of a cliff and threw them down so that all were dashed to pieces. 13 Meanwhile the troops that Amaziah had sent back and had not allowed to take part in the war raided towns belonging to Judah from Samaria to Beth Horon. They killed three thousand people and carried off great quantities of plunder.

14 When Amaziah returned from slaughtering the Edomites, he brought back the gods of the people of Seir. He set them up as his own gods, bowed down to them and burned sacrifices to them. 15 The anger of the Lord burned against Amaziah, and he sent a prophet to him, who said, "Why do you consult this people's gods, which could not save their own people from your hand?" 16 While he was still speaking, the king said to him, "Have we appointed you an adviser to the king? Stop! Why be struck down?" So the prophet stopped but said, "I know that God has determined to destroy you, because you have done this and have not listened to my counsel."

Commentary on 2 Chronicles 25:1-13

(Read 2 Chronicles 25:1-13)

Amaziah was no enemy to religion, but cool and indifferent friend. Many do what is good, but not with a perfect heart. Rashness makes work for repentance. But Amaziah's obedience to the command of God was to his honour. A firm belief of God's all-sufficiency to bear us out in our duty, and to make up all the loss and damage was sustain in his service, will make his yoke very easy, and his burden very light. When we are called to part with any thing for God and our religion, it should satisfy us, that God is able to give us much more than this. Convinced sinners, who have not true faith, always object to self-denying obedience. They are like Amaziah; they say, But what shall we do for the hundred talents? What shall we do if by keeping the sabbath holy we lose so many good customers? What shall we do without this gain? What shall we do if we lose the friendship of the world? Many endeavour to quiet their consciences by the pretence that forbidden practices are necessary. The answer is, as here, The Lord is able to give thee much more than this. He makes up, even in this world, for all that is given up for his sake.

Commentary on 2 Chronicles 25:14-16

(Read 2 Chronicles 25:14-16)

To worship the gods of those whom Amaziah had conquered, who could not help their own worshippers, was the greatest absurdity. If men would consider how unable all those things are to help them, to which they look whenever they forsake God, they would not be such enemies to themselves. The reproof God sent by a prophet was too just to be answered; themselves. The reproof God sent by a prophet was too just to be answered; but he was bidden not to say a word more. The secure sinner rejoices to have silenced his reprovers and monitors; but what comes of it? Those that are deaf to reproof, are ripening for destruction.
