20:1 David’s adultery occurred at this time while he remained in Jerusalem instead of going to battle (2 Samuel 11–12). This story may have been excluded from 1 Chronicles because the book was written to focus on God’s long-term interest in Israel and on the Temple as a symbol of God’s presence among them. The story of David and Bath-sheba did not fit this purpose. The story of Absalom’s rebellion, which occurred between this chapter and the next, was probably omitted for the same reason (2 Samuel 15–18).
20:1 Kings went out to battle following the spring harvest. At this time, farm work eased off, and the armies could live off the land. During the winter, they plotted and planned future conquests. Then, when fair weather permitted, their armies went to war. But David ignored this opportunity. He stayed home and sent Joab out to lead the army. It was during this time of inactivity that he sinned with Bath-sheba. Look for the “springs” in your life, the times when God wants you to respond, take the initiative, and move out to do his will. It is during these critical times that we may be most sensitive to temptation. Resolve to take the action God has prescribed. Don’t give temptation a foothold in your inactivity.
20:1 Rabbah was the capital of the Ammonites and is the site of modern Amman in Jordan.
