281 And it came to pass in those days, that the Philistines gathered their hosts together for warfare, to fight with Israel. And Achish said unto David, Know thou assuredly, that thou shalt go out with me in the host, thou and thy men. 2 And David said to Achish, Therefore thou shalt know what thy servant will do. And Achish said to David, Therefore will I make thee keeper of my head for ever.
3 Now Samuel was dead, and all Israel had lamented him, and buried him in Ramah, even in his own city. And Saul had put away those that had familiar spirits, and the wizards, out of the land. 4 And the Philistines gathered themselves together, and came and encamped in Shunem: and Saul gathered all Israel together, and they encamped in Gilboa. 5 And when Saul saw the host of the Philistines, he was afraid, and his heart trembled greatly. 6 And when Saul inquired of Jehovah, Jehovah answered him not, neither by dreams, nor by Urim, nor by prophets.

Commentary on 1 Samuel 28:1-6
(Read 1 Samuel 28:1-6)
David could not refuse Achish without danger. If he promised assistance, and then stood neuter, or went over to the Israelites, he would behave with ingratitude and treachery. If he fought against Israel, he would sin greatly. It seemed impossible that he should get out of this difficulty with a clear conscience; but his evasive answer, intended to gain time, was not consistent with the character of an Israelite indeed. Troubles are terrors to the children of disobedience. In his distress, Saul inquired of the Lord. He did not seek in faith, but with a double, unstable mind. Saul had put the law in force against those that had familiar spirits, Exodus 22:18. Many seem zealous against, sin, when they are any way hurt by it, who have no concern for the glory of God, nor any dislike of sin as sin. Many seem enemies to sin in others, while they indulge it in themselves. Saul will drive the devil out of his kingdom, yet harbours him in his heart by envy and malice. How foolish to consult those whom, according to God's law, he had endeavoured to root out!
