David said to Achish, Therefore you shall know what your servant will do. Achish said to David, Therefore will I make you keeper of my head for ever.
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.
