Job 9:31

Thine own mouth condemneth thee, and not I: yea, thine own lips testify against thee.

Their webs shall not become garments, neither shall they cover themselves with their works: their works are works of iniquity, and the act of violence is in their hands.

But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.

If I justify myself, mine own mouth shall condemn me: if I say, I am perfect, it shall also prove me perverse.
