1 Samuel 28:1
And it came to pass in those days, that the Philistines gathered their armies together for warfare, to fight with Israel. And Achish said unto David, Know thou assuredly, that thou shalt go out with me to battle, thou and thy men.
And it came to pass in those days,.... That David was in the country of the Philistines:
that the Philistines gathered their armies together: out of their five principalities or lordships:
for warfare to fight with Israel; with whom they were continually at war, and though sometimes there was a cessation of arms, yet never any settled peace; and the Philistines took every opportunity and advantage against them, as they now did; when David was among them, and so had nothing to fear from him, but rather expected his assistance; and Samuel was dead, and Saul in a frenzy:
And Achish said unto David: who seems to have been at the head of the combined armies of the Philistines:
Know thou assuredly that thou shall go with me to battle, thou and thy men; against Israel; which was a trying thing to David, and whereby he was like to be drawn into a dilemma; either to fight against his country, which he could not do conscientiously; or be guilty of ingratitude to Achish, and incur his displeasure, and be liable to be turned out of his country, or treated in a worse manner, even he and his men, to be seized on and cut to pieces by the forces of the Philistines, should he refuse.
