'Righteousness' in the Bible

Solomon said, "You have shown to your servant David my father great loving kindness, according as he walked before you in truth, and in righteousness, and in uprightness of heart with you. You have kept for him this great loving kindness, that you have given him a son to sit on his throne, as it is this day.

then hear in heaven, and do, and judge your servants, condemning the wicked, to bring his way on his own head, and justifying the righteous, to give him according to his righteousness.

Blessed is Yahweh your God, who delighted in you, to set you on the throne of Israel. Because Yahweh loved Israel forever, therefore made he you king, to do justice and righteousness."
