At the beginning of his exile, David had fled to Gath for safety, only to discover that his life was still in danger, and then he had to act like a madman in order to escape (21:10–15). But at that time, David was alone, while now he had two wives and was the commander of 600 valiant soldiers. David was still a deceiver, and “faith is living without scheming.” He deceived Achish concerning three matters: the request for a city, the raids his men conducted, and the desire to fight the king’s battles.
His request for a city (vv. 3–7). Undoubtedly the news had reached the Philistines that Saul was trying to kill David, and so any enemy of Saul would be warmly welcomed in Gath. Achish could make use of David’s tactical skill and the battle-honed skills of his courageous men. But the total number of people David brought with him could well have been between 2,000–3,000 (30:1–3), and that was quite a crowd to drop into the city of Gath.
Actually, David didn’t want to stay in Gath because there the king and his officers could investigate what he was doing, so he requested that the king give him and his people a city of their own. He was very diplomatic in the way he phrased his request, humbling himself before the king (“I am not worthy to live in the royal city.”) and assuring Achish that his services were always available. Happy to get the extra people out of Gath, where they were probably straining the food and water supply, and ready to strengthen his own army, Achish quickly accepted the idea. He gave David Ziklag, a town about twenty-five miles southwest of Gath, on the border of Simeon but under Philistine control. The tribe of Simeon had its inheritance within the tribe of Judah, which explains why Ziklag was associated with both tribes (Josh. 15:31; 19:5). However, since Achish gave the town to David, it belonged to the kings of Judah ever after. There could not have been a better base of operations for David and his men, and they made good use of it.
His reports of the raids (vv. 8–12). Achish thought that David and his band were attacking cities and towns in Judah, when in reality they were raiding the towns and camps of the allies of Achish! David was wiping out the people that Joshua and his successors failed to exterminate when they entered the land, following the orders given by Moses in Deuteronomy 20:16–18. At the same time, he was eliminating the danger of any survivors taking the word to Gath that David was a liar. David took Achish gifts from the spoils of battle and gave him false reports of their activities, and Achish believed him. When word got back to the people of Judah that David was attacking their enemies, this made him even more popular with the leaders.
His responsibility in the battle (28:1–2; 29:1–11). This is the battle in which Saul and his sons were killed (31:1–6), and it was the providential hand of the Lord that kept David and his men from having to participate. Achish assured David that he and his men were expected to fight alongside the Philistine troops, but David’s reply was evasive: “Then you will see for yourself what your servant can do” (28: niv). The king interpreted this to mean, “Until now, you have received only verbal reports of the prowess of me and my men, but this battle will give us opportunity to display our skills before your very eyes.” But is that what David meant? Certainly he wouldn’t fight against his own people, and he probably had an alternate plan in mind. But the king was so impressed that he commissioned David to be his bodyguard for life!
The troops assembled and paraded, the five lords of the Philistines (6:16–17) leading their companies and David and his men bringing up the rear and guarding the king. When the princes (military commanders) of the Philistines saw their king with David and his 600, they protested, “What are these Hebrews doing here?” This question must have shocked Achish because he had the utmost confidence in David. He hastened to assure his commanders that he had watched David for over a year, in fact, from the first day David left Saul (21:10–15), and he trusted him.
The leaders couldn’t argue with their king, but they could suggest a safety measure. They remembered that in a previous battle, some Hebrew soldiers in the Philistine army had deserted their posts and fought for Israel (14:21), and David and his men might do the same thing. True, Saul was David’s enemy, but they might be reconciled and fight together. After all, the people used to sing, “Saul slew his thousands, and David his ten thousands” (28:5; 18:7; 21:11), which suggests that they were once fighting together. The safest thing to do was to send David back to Ziklag, far from the battle, and let him carry on his own military attacks elsewhere.
The king gave the message to David, who continued his deception by appearing to be deeply hurt by the order. Had he not proved himself to his king? He wanted to go out and “fight against the enemies of [his] lord, the king,” another ambiguous statement that the king would interpret in his favor. But who was David’s “lord and king”—King Saul (24:8; 26:17), Achish, or Jehovah? And who were David’s enemies—the Jews or the Philistines? But Achish assumed that he was David’s king, so he ordered him to quietly leave Gath and go back to Ziklag and not to upset the commanders in any way. They had a demanding battle ahead of them and Achish wanted them to be at their best. David obeyed and returned to Ziklag.
Though the Lord was gracious to deliver David and his men from participating in this battle, He isn’t obligated to step in and extricate His people from situations caused by their own sinful decisions. We reap what we sow, and in later years, David suffered from being deceived by members of his staff and even of his own family.
