'Righteous' in the Bible

The LORD will repay him for his bloodshed because, without my father David's consent he attacked and murdered two men more righteous and better than he, Ner's son Abner, the commander of Israel's army and Jether's son Amasa, commander of Judah's army.

then listen in heaven, act, and judge your servants, condemning the wicked by bringing back to him the consequences of his choices and by justifying the righteous by recompensing him according to his righteousness.
