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.
      II. The expectation Achish had of assistance from David in this war, and the encouragement David gave him to expect it: "Thou shalt go with me to battle," says Achish. "If I protect thee, I may demand service from thee;" and he will think himself happy if he may have such a man as David on his side, who prospered whithersoever he went. David gave him an ambiguous answer: "We will see what will be done; it will be time enough to talk of that hereafter; but surely thou shalt know what thy servant can do" (1 Samuel 28:2; 1 Samuel 28:2), that is, "I will consider in what post I may be best able to serve thee, if thou wilt but give me leave to choose it." Thus he keeps himself free from a promise to serve him and yet keeps up his expectation of it; for Achish took it in no other sense than as an engagement to assist him, and promised him, thereupon, that he would make him captain of the guards, protector, or prime-minister of state.
