Samuel judged Israel all the days of his life.
We have here a short account of the further good services that Samuel did to Israel. Having parted them from their idols, and brought them home to their God, he had put them into a capacity of receiving further benefits by his ministry. Having prevailed in that, he becomes, in other instances, a great blessing to them; yet, writing it himself, he is brief in the relation.
Commenting on 1 Samuel 7:13-17
And Samuel judged Israel all the days of his life. Not only before Saul was made king, but afterwards; for though he had not the exercise of the supreme government of the nation, yet he might act as a judge under Saul, and hear and try causes brought before him, and execute justice and judgment; and as a prophet he taught and instructed the people...
Samuel judged Israel all the days of his life - Samuel is supposed to have lived one hundred years; he did not begin to judge Israel till he was about forty years of age; and if he was one hundred years of age when he died, he must have been a judge sixty years, and consequently filled that office during the whole of Saul's reign.
