Verses 1–2
David in the Army of the Philistines
Aphek is in Israel. There the Philistines gather together. These are the preparatory actions for decisive moments for both David and Saul. The result is grace for one and destruction for the other. Such a difference we see with Peter and Judas. They have both left the Lord, but Peter is restored while Judas faces his downfall. The difference is the possession of the new life.
David is with the Philistines, and with enemies he stands up against the people of God. This is the result of his life in the lie. David is not only a servant of Achish, but he seems to be his friend. That is how deep he sank.
