'Righteous' in the Bible

And they were singing the song of Moses, God's servant, and the song of the Lamb. Their words were, "Great and wonderful are Thy works, O Lord God, the Ruler of all. Righteous and true are Thy ways, O King of the nations.

And I heard the angel of the waters say, "Righteous art Thou, who art and wast, the holy One, because Thou hast thus taken vengeance.

And I heard a voice from the altar say, "Even so, O Lord God, the Ruler of all, true and righteous are Thy judgments."

And she was permitted to array herself in fine linen, shining and spotless; the fine linen being the righteous actions of God's people.

Let the dishonest man act dishonestly still; let the filthy make himself filthy still; let the righteous practise righteousness still; and let the holy be made holy still."
