Had yet war again. — This, like the preceding narrative, bears no note of time except that it occurred after some other wars with the Philistines; but this is only to say that it was after David ascended the throne. From the latter part of 2 Samuel 21:17 it is plain that it must have been after David had become king of all Israel, and probably after he had become somewhat advanced in years. In 1 Chronicles 20:4-8 much the same paragraph is placed immediately after the war with Ammon; but this seems to be a mere juxta-position rather than designed as a chronological sequence.
