John Wesley on 1 Samuel 12:2

Walketh - Ruleth over you. To him I have fully resigned my power, and own myself one of his subjects. Old - And therefore unable to bear the burden of government. My sons - Or, among you, in the same states private persons, as you are; if they have injured any of you, the law is now open against them; any of you may accuse them, your king can punish them, I do not intercede for them. Walked before you - That is, been your guide and governor; partly, as a prophet; and partly, as a judge.
