Once again, David wanted to show kindness, but this time his attempt led to war instead of peace. His overtures to his neighbor were misunderstood, and David had to defend his own honor as well as the honor of the Lord and His people.
A public offense (vv. 1–5). King Saul’s first military victory was over Nahash and the Ammonite army when they attacked Jabesh Gilead (1 Sam. 11). Like the Ammonites, the Moabites were descendants of Lot (Gen. 19:30ff.) and therefore relatives of the Jews. How did David become friendly with the Ammonites when his predecessor was at war with them? It probably occurred when David was in exile and appeared to be at war with Saul. During those “outlaw years,” David tried to build a network of friendships outside Israel that he hoped would help him when he became king. The phrase “show kindness” can carry the meaning of “make a covenant,” so it may have been David’s desire not only to comfort Hanun but also to make a treaty with him.
David sent a delegation of court officials to Hanun, but immaturity and ignorance triumphed over wisdom and common sense. The inexperienced new king listened to his suspicious advisers and treated David’s men as though they were spies. (Years later, Solomon’s son Rehoboam would make a similar mistake and follow unwise counsel. See 1 Kings 12.) The Ammonites shaved the ambassadors’ faces, leaving but one side of each beard intact, and then cut the men’s official garments off at the waist. Jewish men were supposed to keep their beards intact (Lev. 19:27; 21:5; Deut. 14:1–2), and to tamper with a man’s beard was a great insult. All Jews were to be dressed modestly, so exposing the men’s bodies was even more embarrassing. It was treating them as though they were prisoners of war (Isa. 20:3–4), and it also meant removing some of the tassels on their garments that identified them as Jews (Deut. 22:12; Num. 15:37–41).
The first battle (vv. 6–14). The members of the delegation could easily secure other garments, but it would take time for their beards to grow, so they stayed in Jericho until they looked presentable. However, new beards couldn’t erase old wounds. When King Hunan allowed his officials to mistreat the delegation, he not only insulted the men personally, but he also insulted King David who sent them and the nation they represented. In short, it was a declaration of war.
But King Hunan wasn’t prepared for war, especially against a seasoned general like Joab and a famous king like David, so he paid a thousand talents of silver (1 Chron. 19:6) to hire troops from the north, including Syrians and Arameans, nations that David eventually defeated (8:12). These 33,000 soldiers joined with the Ammonite army in attacking the Jewish army. Actually, Joab faced two armies who were using a pincer movement to defeat Israel, with the Syrians and Arameans coming from the north and the Ammonites coming from the south. Joab wisely divided his forces and put his brother Abishai in charge of the southern front, and with the Lord’s gracious help, Joab so defeated the northern troops that his victory frightened the southern troops to flee to Rabbath, the fortified capital city of Ammon.
The second battle (vv. 15–19). David came personally to lead the battle against the Syrians, and he and the army of Israel defeated them, and the Syrians became vassal states in David’s growing empire. Joab wisely waited to set up a siege against the Ammonite capital of Rabbah at that time, so he waited to renew the attack in the spring of the year (11:1). He took the city and David came to finish the siege and claim the honors (12:26–31). It was while Joab and his men were besieging Rabbah that David remained in Jerusalem and committed adultery with Bathsheba.
David indeed was a man of war and fought the battles of the Lord, and the Lord was with him to give him victory. He extended the Israelite empire to the River of
