'Unrighteous' in the Bible

Thou shalt not take up a false report: put not thy hand with the wicked to be an unrighteous witness.

If an unrighteous witness rise up against any man to testify against him of wrong-doing,

Surely such are the dwellings of the unrighteous, And this is the place of him that knoweth not God.

Let mine enemy be as the wicked, And let him that riseth up against me be as the unrighteous.

And I brake the jaws of the unrighteous, And plucked the prey out of his teeth.

Is it not calamity to the unrighteous, And disaster to the workers of iniquity?

Unrighteous witnesses rise up; They ask me of things that I know not.

Rescue me, O my God, out of the hand of the wicked, Out of the hand of the unrighteous and cruel man.

Woe unto them that decree unrighteous decrees, and to the writers that write perverseness;

let the wicked forsake his way, and the unrighteous man his thoughts; and let him return unto Jehovah, and he will have mercy upon him; and to our God, for he will abundantly pardon.
