'Unrighteous' in the Bible

If an unrighteous witness rise up against any man to testify against him of wrongdoing,

Surely such are the dwellings of the unrighteous. This is the place of him who doesn't know God."

"Let my enemy be as the wicked. Let him who rises up against me be as the unrighteous.

I broke 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 about things that I don't know about.

Rescue me, my God, from the hand of the wicked, from the hand of the unrighteous and cruel man.

Woe to those who decree unrighteous decrees, and to the writers who write oppressive decrees;

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