Thematic Bible: Is refused permission to accompany the philistines to battle against the israelites

At that time the Philistines assembled their army for war to fight against Israel. Achish told David, "You know, of course, that you and your men will go out with me into the battle." David told Achish, "Very well, you will now see what your servant will do." Achish told David, "Very well, I'll appoint you as my permanent bodyguard."
