5 Amaziah called the people of Judah together and assigned them according to their families to commanders of thousands and commanders of hundreds for all Judah and Benjamin. He then mustered those twenty years old or more and found that there were three hundred thousand men fit for military service, able to handle the spear and shield. 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.

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.
