2 Chronicles 25:5-6

5Then Amaziah brought all the people of Judah together. For each of their clans he chose officers to lead groups of 1,000 men and groups of 100 men. He did that for the clans of Judah's tribe and the clans of Benjamin's tribe. He counted all the men who were 20 years old or older who could fight with spears and shields. There were 300,000 of them.

6He also paid 3,500 kilograms of silver for 100,000 soldiers from Israel to join his army.
