1 Samuel 12:1

And now, behold, the king walketh before you: and I am old and grayheaded; and, behold, my sons are with you: and I have walked before you from my childhood unto this day.

Behold, here I am: witness against me before the LORD, and before his anointed: whose ox have I taken? or whose ass have I taken? or whom have I defrauded? whom have I oppressed? or of whose hand have I received any bribe to blind mine eyes therewith? and I will restore it you.

And they said, Thou hast not defrauded us, nor oppressed us, neither hast thou taken ought of any man's hand.

And he said unto them, The LORD is witness against you, and his anointed is witness this day, that ye have not found ought in my hand. And they answered, He is witness.
