The verse belongs to the parallel account to the events in 2 Samuel 5, recounting David becoming king over all Israel. Within that history it preserves the names of David's sons, forming part of the careful record of God's people and of David's family. As part of Chronicles it belongs to the history of David that assumes knowledge of the preceding books of the Bible. That history supplies what was left out of Samuel and Kings. It gives many new and important facts.
