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

Thy own mouth shall condemn thee, and not I: and thy own lips shall answer thee.

Thy mouth declareth thee wicked, and not I, And thy lips testify against thee.

Your own mouth comdemns you, and not I: yes, your own lips testify against you.

It is by your mouth, even yours, that you are judged to be in the wrong, and not by me; and your lips give witness against you.

Thine own mouth condemneth thee - That is, the sentiments which you have uttered show that you cannot be a pious man.

Thine own mouth condemneth thee, and not I,.... Or shows thee to be a wicked person, guilty of things charged upon thee; out of thine own mouth thou art convicted, there needs no other evidence to be brought against thee, that is sufficient: and thou savest me, and any other, the trouble of passing the sentence of condemnation upon thee; thou hast done it thyself, thine own mouth is judge and jury, and brings in the verdict, and pronounces it, as well as is the witness, as follows, and is instead of a thousand witnesses, Job 9:20;
yea, thine own lips testify against thee; and therefore there were no need of producing any other testimony; what he had said showed that his talk was vain and unprofitable, unbecoming a wise man, and tending to make null and void the fear of God among men, to discourage all religious exercises, and particularly prayer before God.

No pious man would utter such sentiments.
