5 King Amaziah organized all the men of the tribes of Judah and Benjamin into army units, according to the clans they belonged to, and placed officers in command of units of a thousand and units of a hundred. This included all men twenty years of age or older, 300,000 in all. They were picked troops, ready for battle, skilled in using spears and shields.
6 In addition, he hired 100,000 soldiers from Israel at a cost of about four tons of silver.
7 But a prophet went to the king and said to him, “Don't take these Israelite soldiers with you. The Lord is not with these people from the Northern Kingdom.
8 You may think that they will make you stronger in battle, but it is God who has the power to give victory or defeat, and he will let your enemies defeat you.”
9 Amaziah asked the prophet, “But what about all that silver I have already paid for them?”The prophet replied, “The Lord can give you back more than that!”
10 So Amaziah sent the hired troops away and told them to go home. At this they went home, bitterly angry with the people of Judah.
11 Amaziah summoned up his courage and led his army to Salt Valley. There they fought and killed ten thousand Edomite soldiers
