'Unrighteous' in the Bible

And the lord praised the unrighteous steward because he had done prudently. For the sons of this world are, for their own generation, more prudent than the sons of light.

He that is faithful in the least is faithful also in much; and he that is unrighteous in the least is unrighteous also in much.

If therefore ye have not been faithful in the unrighteous mammon, who shall entrust to you the true?

But if our unrighteousness commend God's righteousness, what shall we say? Is God unrighteous who inflicts wrath? I speak according to man.

Do ye not know that unrighteous persons shall not inherit the kingdom of God? Do not err: neither fornicators, nor idolaters, nor adulterers, nor those who make women of themselves, nor who abuse themselves with men,

For God is not unrighteous to forget your work, and the love which ye have shewn to his name, having ministered to the saints, and still ministering.
