(1) After the year was expired. — Literally, as in margin, at the return of the year. This refers back to 2 Samuel 10:14. Joab had spent the winter or rainy season at Jerusalem; now he returns to Ammon. David had evidently hurried his campaign against Hadarezer to prevent the junction of his foes, and Joab had probably been sent at first with only a small force to hold the Ammonites in check. With the speedy and successful close of David’s own operations, he returned to Jerusalem, while the bulk of the army was sent to join Joab. By the curious insertion of a letter the Hebrew text reads “when angels (or messengers) go forth.” It is corrected in the margin.
Destroyed the children. — 1 Chronicles 20:1, explains “wasted the country of the children.” After the custom of ancient warfare, while the army was besieging Rabbah, foraging parties were sent out to lay waste the country and cut off any stragglers. Comp. 1 Samuel 13:17-18.
