Charles Ellicott Commentary 1 Samuel 7:13

"So the Philistines were subdued, and they came no more within the border of Israel: and the hand of Jehovah was against the Philistines all the days of Samuel." — 1 Samuel 7:13 (ASV)

So the Philistines were subdued. —The work of Samuel had been thorough. It was no mere solitary victory, this success of Israel at Ebenezer, but was the sign of a new spirit in Israel, which animated the nation during the lifetime of Samuel, and the reigns of David and Solomon and the great Hebrew kings. The petty jealousies had disappeared and had given place to a great national desire for unity.

In the various tribal districts, it was no longer the glory and prosperity of Judah, Ephraim, or Benjamin, but the glory and prosperity of Israel that was aimed at. The old idol worship of Canaan, which corrupted and degraded every nationality that practiced it, was largely swept away from among the chosen people, while the pure religion of the Eternal of Hosts was no longer confided solely to the care and guardianship of the tribe of Levi, which had shown itself unworthy of the mighty trust.

The Levites still ministered in the sanctuary; and when the Temple took its place, they alone officiated in its sacred courts. The chosen race of Aaron—in the family first of Ithamar, then of Eleazar—alone wore the jewels and the official robe of the high priest. However, in religious matters, the power of the priestly tribe was never again supreme in the Land of Promise. From the days of Samuel, a new order—that of the Prophets, whose exact functions regarding the ritual of the worship of the Eternal were undefined—was acknowledged by the people as the regular medium of communication with the Jewish King of Israel.

The hand of the Lord was against the Philistines. —The Philistines never entirely recovered their supremacy in Canaan. It is true, there was a long, fierce struggle. However, with the exception of the short period immediately preceding Saul's election and the temporary disasters of the children of Israel (which were the punishments for that king’s disobedience), from this time forward the power of the Philistines gradually decayed, while the strength of Israel steadily increased. This continued until King David completely subdued them, and the old oppressors of Israel were absorbed into the subject races of Canaan.
