'Unrighteous' in the Bible

Thou shalt not raise a false report: put not thine hand with the wicked to be an unrighteous witness.

Let mine enemy be as the wicked, and he that riseth up against me as the unrighteous.

Deliver 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 that write grievousness which they have prescribed;

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

If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches?

But if our unrighteousness commend the righteousness of God, what shall we say? Is God unrighteous who taketh vengeance? (I speak as a man)

Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,

For God is not unrighteous to forget your work and labour of love, which ye have shewed toward his name, in that ye have ministered to the saints, and do minister.
