'Righteous' in the Bible

Righteous art Thou, O Jehovah, When I plead towards thee, Only, judgments do I speak with Thee, Wherefore did the way of the wicked prosper? At rest have been all treacherous dealers.

And, O Jehovah of Hosts, trier of the righteous, Beholder of reins and heart, I do see Thy vengeance out of them, For unto Thee I have revealed my cause.

Lo, days are coming -- an affirmation of Jehovah, And I have raised to David a righteous shoot, And a king hath reigned and acted wisely, And done judgment and righteousness in the earth.
