5 Then Amaziah organized the army, assigning generals and captains for all Judah and Benjamin. He took a census and found that he had an army of 300,000 select troops, twenty years old and older, all trained in the use of spear and shield. 6 He also paid about 7,500 pounds of silver to hire 100,000 experienced fighting men from Israel. 7 But a man of God came to him and said, "Your Majesty, do not hire troops from Israel, for the Lord is not with Israel. He will not help those people of Ephraim! 8 If you let them go with your troops into battle, you will be defeated by the enemy no matter how well you fight. God will overthrow you, for he has the power to help you or to trip you up." 9 Amaziah asked the man of God, "But what about all that silver I paid to hire the army of Israel?" The man of God replied, "The Lord is able to give you much more than this!" 10 So Amaziah discharged the hired troops and sent them back to Ephraim. This made them very angry with Judah, and they returned home in a great rage.

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.
