Verses 1–6
First Samuel - Chapter 28
Israelite-Philistine War Renewed, vs. 1-6
When David had been in the Philistine country for sixteen months Achish and the other four lords of the Philistines determined to renew the centuries-long conflict with Israel. They had successfully ousted Israel from the coastal areas and were continually making incursions into the hill country and mountains of Israel, trying often with success, to extort tribute.
By this time Achish was fully persuaded of the loyalty of David to him, and informed him that he and his men would surely accompany him into battle against Israel. David replied with ambiguity, that Achish would see what David could do. It might have been interesting to know just what David would have done had he been allowed to carry through with Achish’s purpose. Achish promised to make David the keeper of his head for ever, which means to make David the guardian of his life. One might speculate that David had also been the keeper of Goliath’s head, and might perhaps have eventually kept the head of Achish in like manner (see 1 Samuel 17:54).
At verse 3 the scene shifts back to Israel in premonition of the final battle of Saul and his desperation before his death. The reader is reminded that Samuel has been sometime dead and honorably buried by the mourning Israelites in his own city of Ramah. Thus he was no longer available to advise and encourage the people or king against the Philistines. Furthermore consultation of the occult was also difficult, for Saul in his false piety had put to death the mediums and wizards, so that any remaining alive had gone underground.
When therefore the Philistines invaded the land of Israel with a mighty host Saul was terribly afraid, and his heart almost failed him. It appears he had a premonition of the end. Saul tried to inquire of the Lord, but he was long since out of favor with Him. God was not on speaking terms with the disobedient and rebellious king. So Saul had no prophet, got no dream, and received no answer through the Urim of the priests, the chief of whom he had killed (1 Samuel 22:6 ff).
