The Philistines gather their armies together against Israel, and encamp at Aphek; while the Israelites encamp at Jezreel, Sa1 29:1. The lords of the Philistines refuse to let David go to battle with them, lest he should betray them, Sa1 29:2-5. Achish expresses his confidence in David; but begs him to return, Sa1 29:6-10. David and his men return, Sa1 29:11.
