1-а Самуїлова 28:8

David in the Army of the Philistines. Attack upon Israel. Saul and the Witch of Endor - 1 Samuel 28 The danger into which David had plunged through his flight into the land of the Philistines, and still more through the artifice with which he had deceived the king Achish as to his real feelings, was to be very soon made apparent to him. For example, when the Philistines went to war again with Israel, Achish summoned him to go with his men in the army of the Philistines to the war against his own people and land, and David could not disregard the summons. But even if he had not brought himself into this danger without some fault of his own, he had at any rate only taken refuge with the Philistines in the greatest extremity; and what further he had done, was only done to save his own life. The faithful covenant God helped him therefore out of this trouble, and very soon afterwards put an end to his persecution by the fact that Saul lost his life in the war.

Preparations are herein making for that war which will put an end to the life and reign of Saul, and so make way for David to the throne. In this war, I. The Philistines are the aggressors and Achish their king makes David his confidant (Sa1 28:1, Sa1 28:2). II. The Israelites prepare to receive them, and Saul their king makes the devil his privy-counsellor, and thereby fills the measure of his iniquity. Observe, 1. The despairing condition which Saul was in (Sa1 28:3-6). 2. The application he made to a witch, to bring him up Samuel (Sa1 28:7-14). 3. His discourse with the apparition (Sa1 28:15-19). The damp it struck upon him (Sa1 28:20-25).
