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, 1 Sam. 28:1, 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, 1 Sam. 28:3-6. 2. The application he made to a witch, to bring him up Samuel, 1 Sam. 28:7-14. 3. His discourse with the apparition, 1 Sam. 28:15-19. The damp it struck upon him, 1 Sam. 28:20-25.
