'Righteousness' in the Bible

And Solomon said, Thou hast showed unto thy servant David my father great lovingkindness, according as he walked before thee in truth, and in righteousness, and in uprightness of heart with thee; and thou hast kept for him this great lovingkindness, that thou hast given him a son to sit on his throne, as it is this day.

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

Blessed be Jehovah thy God, who delighted in thee, to set thee on the throne of Israel: because Jehovah loved Israel for ever, therefore made he thee king, to do justice and righteousness.
