'Righteous' in the Bible

And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, O Lord God, the Almighty; righteous and true are thy ways, thou King of the ages.

Who shall not fear, O Lord, and glorify thy name? for thou only art holy; for all the nations shall come and worship before thee; for thy righteous acts have been made manifest.

And I heard the angel of the waters saying, Righteous art thou, who art and who wast, thou Holy One, because thou didst thus judge:

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

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

And it was given unto her that she should array herself in fine linen, bright and pure: for the fine linen is the righteous acts of the saints.

And I saw the heaven opened; and behold, a white horse, and he that sat thereon called Faithful and True; and in righteous he doth judge and make war.

He that is unrighteous, let him do unrighteousness still: and he that is filthy, let him be made filthy still: and he that is righteous, let him do righteousness still: and he that is holy, let him be made holy still.
