The Philistines were now preparing a new campaign under Achish against Saul and his kingdom, and Achish determined that David should go with him; further, that he should go in the capacity of "keeper of his head," or captain of his body guard, and that this should not be a temporary arrangement, but permanent--"for ever." It is difficult for us to conceive the depth of the embarrassment into which this intimation must have plunged David. We must bear in mind how scrupulous and sensitive his conscience was as to raising his hand against the Lord's anointed; and we must take into account the horror he must have felt at the thought of rushing in deadly array against his own dear countrymen, with most of whom he had had no quarrel, and who had never done him any harm. When Achish made him head of his body guard he paid a great compliment to his fidelity and bravery; but in proportion as the post was honourable it was disagreeable and embarrassing. For David and his men would have to fight close to Achish, under his very eye; and any symptoms of holding back from the fray--any inclination to be off, or to spare the foe, which natural feeling might have dictated in the hour of battle, must be resisted in presence of the king. Perhaps David reckoned that if the Israelites were defeated by the Philistines he might be able to make better terms for them--might even be of use to Saul himself, and thus render such services as would atone for his hostile attitude. But this was a wretched consolation. David was entangled so that he could neither advance nor retreat. Before him was GOD, closing His path in front; behind him was MAN, closing it in rear; and we may well believe he would have willingly given all he possessed if only his feet could have been clear and his conscience upright as before.
