Amaziah was twenty-five years old when he became king, and he reigned in Jerusalem twenty-nine years. His mother’s name was Jehoaddan; she was from Jerusalem.
He did what was right in the eyes of the LORD, but not wholeheartedly.
After the kingdom was firmly in his control, he executed the officials who had murdered his father the king.
Yet he did not put their children to death, but acted in accordance with what is written in the Law, in the Book of Moses, where the LORD commanded: “Parents shall not be put to death for their children, nor children be put to death for their parents; each will die for their own sin.”
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.
He also hired a hundred thousand fighting men from Israel for a hundred talents of silver.
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.
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.”
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.”
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.
Amaziah then marshaled his strength and led his army to the Valley of Salt, where he killed ten thousand men of Seir.
