'Righteous' in the Bible

Righteous art thou, O LORD, when I plead with thee: yet let me talk with thee of thy judgments: Wherefore doth the way of the wicked prosper? wherefore are all they happy that deal very treacherously?

But, O LORD of hosts, that triest the righteous, and seest the reins and the heart, let me see thy vengeance on them: for unto thee have I opened my cause.

Behold, the days come, saith the LORD, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth.
