2 Chronicles 13:17
And Abijah and his people slew them with a great slaughter: so there fell down slain of Israel five hundred thousand chosen men. And Abijah and his people slew them with a great slaughter: so there fell down slain of Israel five hundred thousand chosen men.
After the division of the kingdom the verse falls in the reign of Abijah over Judah, at a time when Israel under Jeroboam had turned away from God through the golden calves and had largely ignored the appeals of God's prophets. In its immediate context it belongs to the war between Judah under Abijah and Israel under Jeroboam, in which Judah conquered. It records a decisive victory in which Abijah and his smaller army of Judah inflicted a great slaughter on Jeroboam's larger army of Israel, with five hundred thousand chosen men falling slain.
The victory came when Judah was attacked from front and rear; Abijah called on the Lord, the priests sounded the trumpets and the people shouted, and the Lord helped them. The conflict in the chapter parallels the American Civil War, with Jeroboam's revolt and attempt to rule Judah corresponding to the South's secession and effort to extend its rule over the North, and Abijah's resistance providing an example for the Union. The lesson drawn from that parallel is that the rebellion would have ended sooner if the government had followed Abijah's example and had not supported Southern slavery.
