2 Samuel 11:1
After the year was expired - The next spring after the escape of the Ammonites into their city II Samuel 10:14.
The children of Ammon - The marginal reference supplies the word "the land of," which is obviously the right reading.
David tarried at Jerusalem - The Syrians being subdued, the war with Ammon was not of sufficient moment to require David' s personal presence. The whole section relating to David' s adultery and Uriah' s death, from this verse to II Samuel 12:26, is omitted in the Book of Chronicles.
