1 Samuel 7:13

So the Philistines were subdued
Not that their country was conquered, or they made subject and become tributaries to Israel; but they were so humbled, as not to attempt to give the people of Israel any further trouble and distress, who were now delivered from their oppression and tyranny:

and came no more into the coast of Israel;
at this time they did not gather together their forces dispersed, nor raise and bring a new army into the land of Israel; they contented themselves with placing garrisons on the coast, but did not attempt to enter and invade them any more; that is, for a long time, even until Samuel was grown old, and the people would have a king, and had one, which offended the Lord, and then he suffered them to be distressed by them again; but while Samuel was alone governor they came no more, though they did quickly after Saul was made king, as it follows:

the hand of the Lord was against the Philistines all the days of
Samuel;
not all the days of his life, but all the days of his sole government, which restrained them from making incursions into the land of Israel; and indeed in later times, when they did come forth to make war with them, the battle was against them during the times of Samuel.
