'Righteous' in the Bible

Righteous art thou, Jehovah, when I plead with thee; yet will I speak with thee of thy judgments. Wherefore doth the way of the wicked prosper? wherefore are all they at ease that deal very treacherously?

And thou, Jehovah of hosts, who triest the righteous, who seest the reins and the heart, let me see thy vengeance on them; for unto thee have I revealed my cause.

Behold, the days come, saith Jehovah, when I will raise unto David a righteous Branch, who shall reign as king, and act wisely, and shall execute judgment and righteousness in the land.
