¹³ Jeroboam had sent an ambush around to come on them from behind; thus his troops^[a] were in front of Judah, and the ambush was behind them. ¹⁴ When Judah turned, the battle was in front of them and behind them. They cried out to the Lord, and the priests blew the trumpets.^{(B) 15} Then the people of Judah raised the battle shout. And when the people of Judah shouted, God defeated Jeroboam and all Israel before Abijah and Judah.^{(C) 16} The Israelites fled before Judah, and God gave them into their hands.^{(D) 17} Abijah and his army defeated them with great slaughter; five hundred thousand picked men of Israel fell slain.

⁹ When you go to war in your land against the adversary who oppresses you, you shall sound an alarm with the trumpets, so that you may be remembered before the Lord your God and be saved from your enemies.^(A)
