2 Chronicles 25:5-13

⁵Then Amazi'ah assembled the men of Judah, and set them by fathers' houses under commanders of thousands and of hundreds for all Judah and Benjamin. He mustered those twenty years old and upward, and found that they were three hundred thousand picked men, fit for war, able to handle spear and shield. ⁶He hired also a hundred thousand mighty men of valor from Israel for a hundred talents of silver. ⁷But a man of God came to him and said, "O king, do not let the army of Israel go with you, for the LORD is not with Israel, with all these E'phraimites. ⁸But if you suppose that in this way you will be strong for war, God will cast you down before the enemy; for God has power to help or to cast down." ⁹And Amazi'ah said to the man of God, "But what shall we do about the hundred talents which I have given to the army of Israel?" The man of God answered, "The LORD is able to give you much more than this." ¹⁰Then Amazi'ah discharged the army that had come to him from E'phraim, to go home again. And they became very angry with Judah, and returned home in fierce anger. ¹¹But Amazi'ah took courage, and led out his people, and went to the Valley of Salt and smote ten thousand men of Se'ir. ¹²The men of Judah captured another ten thousand alive, and took them to the top of a rock and threw them down from the top of the rock; and they were all dashed to pieces. ¹³But the men of the army whom Amazi'ah sent back, not letting them go with him to battle, fell upon the cities of Judah, from Sama'ria to Beth-hor'on, and killed three thousand people in them, and took much spoil.
