It happened in those days, that the Philistines gathered their hosts together for warfare, to fight with Israel. Achish said to David, Know you assuredly, that you shall go out with me in the host, you and your men.
David continued to be a blessing to Israel as he obeyed God in Ziklag, without giving any real help to Israel’s enemy, the Philistines. This plan of David’s, while yielding some positive benefits, involved him in deception and lying, plus leaving him vulnerable to Achish if the Philistine king learned what was really happening.
