These verses conclude the battle narrative in Abijah’s reign (2 Chronicles 13), where Judah faces the larger northern army under Jeroboam. Earlier in the chapter Abijah’s speech contrasts Judah’s worship and leadership with Israel’s rival claims, and the battle is depicted as involving tactics, alarm cries, and divine help. Verses 16–18 function as the wrap-up: they report the rout, quantify the defeat, and interpret the result with a clear cause given by the narrator. The section sets up the remainder of the chapter, which briefly notes Judah’s further advantage and Abijah’s later death.
