This verse appears to contradict 2 Samuel 21:19, which states Elhanan killed Goliath himself. However, scholars explain that the account in Chronicles is likely a clarification. The text in Samuel is thought to contain a copyist's error, and the Chronicler, using other historical sources, provides the more precise record: Elhanan killed Goliath's brother, Lahmi, preserving David's unique victory over Goliath.
