1 Samuel 12:3

Behold — I here present myself before the Lord, and before your king, ready to give an account of all my administrations. And this protestation Samuel makes of his integrity, not out of ostentation; but for his own just vindication, that the people might not hereafter for the defence of their own irregularities, reproach his government, and that being publickly acquitted from all faults in his government, he might more freely reprove the sins of the people, and, particularly, that sin of theirs in desiring a king, when they had so little reason for it.
