2 Chronicles 25:5-10

Amaziah organized Judah and sorted out Judah and Benjamin by families and by military units. Men twenty years and older had to register—they ended up with 300,000 judged capable of military service. In addition he hired 100,000 soldiers from Israel in the north at a cost of about four and a half tons of silver. A holy man showed up and said, “No, O King—don’t let those northern Israelite soldiers into your army; GOD is not on their side, nor with any of the Ephraimites. Instead, you go by yourself and be strong. God and God only has the power to help or hurt your cause.” But Amaziah said to the holy man, “But what about all this money—these tons of silver I have already paid out to hire these men?” “GOD’s help is worth far more to you than that,” said the holy man. So Amaziah fired the soldiers he had hired from the north and sent them home. They were very angry at losing their jobs and went home seething.
