The true test of responsibility is accountability. Samuel gave a proper account when he was to retire from being a leader in Israel.
In 1 Samuel 12:3, Samuel called the people of Israel together and asked them.Whose ox have i taken?Whose donkey have i taken or who gave me a bribe that made keep my mouth shut? in verse 4 the people responded you have never cheated or oppressed us and you have never taken even a single bribe. What a testimony!
