'Righteous' in the Bible

And Jehovah said unto me, Backsliding Israel hath showed herself more righteous than treacherous Judah.

Righteous art thou, O Jehovah, when I contend with thee; yet would I reason the cause with thee: wherefore doth the way of the wicked prosper? wherefore are all they at ease that deal very treacherously?

But, O Jehovah of hosts, that triest the righteous, that seest the heart and the mind, let me see thy vengeance on them; for unto thee have I revealed my cause.

Behold, the days come, saith Jehovah, that I will raise unto David a righteous Branch, and he shall reign as king and deal wisely, and shall execute justice and righteousness in the land.
