'Righteous' in the Bible

And they sing the song of Moses bondman of God, and the song of the Lamb, saying, Great and wonderful are thy works, Lord God Almighty; righteous and true are thy ways, O King of nations.

And I heard the angel of the waters saying, Thou art righteous, who art and wast, the holy one, that thou hast judged so;

And I heard the altar saying, Yea, Lord God Almighty, true and righteous are thy judgments.

for true and righteous are his judgments; for he has judged the great harlot which corrupted the earth with her fornication, and has avenged the blood of his bondmen at her hand.

Let him that does unrighteously do unrighteously still; and let the filthy make himself filthy still; and let him that is righteous practise righteousness still; and he that is holy, let him be sanctified still.
