2 Samuel 8:1

Smote the Philistines. After David had been established on the throne he enjoyed a period of peace that was utilized for the organization and upbuilding of his kingdom. Realizing the strength of Israel, the surrounding nations refrained from attack, and David contented himself with affairs within his realm. At length, however, he decided to reduce his enemies to submission so that they would not be in a position to attack whenever the opportunity might present itself. The Philistines were defeated and made tributary, and part of their territory was annexed to Israel.

Metheg-ammah. The meaning of this name is obscure. Some interpret it as “bridle of the mother city,” “bridle” probably being used in the sense of authority. According to the parallel passage, David took “Gath and her towns out of the hand of the Philistines” (1 Chron. 18:1). Gath, the mother city, the metropolis of the Philistines, is thus probably referred to. This important place was now annexed to Israel. Its retention by David would denote the complete subservience of the Philistines to Israel.
