2 Chronicles 25:5-16 - Amaziah's Campaign Against Edom
5 Moreover, Amaziah assembled Judah, and made them captains over thousands, and captains over hundreds, according to the houses of their fathers, throughout all Judah and Benjamin: and he numbered them from twenty years old and above, and found them three hundred thousand choice men, able to go forth to war, that could handle spear and shield. 6 He hired also a hundred thousand mighty men of valor out of Israel for a hundred talents of silver.
7 But there came a man of God to him, saying, O king, let not the army of Israel go with thee; for the LORD is not with Israel, to wit, with all the children of Ephraim. 8 But if thou wilt go, do it, be strong for the battle: God will make thee fall before the enemy: for God hath power to help, and to cast down.
9 And Amaziah said to the man of God, But what shall we do for the hundred talents which I have given to the army of Israel? And the man of God answered, The LORD is able to give thee much more than this.
10 Then Amaziah separated them, to wit, the army that had come to him out of Ephraim, to go home again: wherefore their anger was greatly kindled against Judah, and they returned home in great anger.
11 And Amaziah strengthened himself, and led forth his people, and went to the valley of salt, and smote of the children of Seir ten thousand. 12 And other ten thousand left alive the children of Judah carried away captive, and brought them to the top of the rock, and cast them down from the top of the rock, that they were all broken in pieces.
13 But the soldiers of the army whom Amaziah sent back, that they should not go with him to battle, fell upon the cities of Judah, from Samaria even to Beth-horon, and smote three thousand of them, and took much spoil.
14 Now it came to pass, after that Amaziah had come from the slaughter of the Edomites, that he brought the gods of the children of Seir, and set them up to be his gods, and bowed himself before them, and burned incense to them. 15 Wherefore the anger of the LORD was kindled against Amaziah, and he sent to him a prophet, who said to him, Why hast thou sought after the gods of the people, which could not deliver their own people out of thy hand?
16 And it came to pass, as he talked with him, that the king said to him, Art thou made of the king's council? forbear? why shouldst thou be smitten? Then the prophet forbore, and said, I know that God hath determined to destroy thee, because thou hast done this, and hast not hearkened to my counsel.
