'Defrauded' in the Bible

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.
