'Righteousness' in the Bible

And Solomon said, Thou hast shewn unto thy servant David my father great loving-kindness, 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 loving-kindness, that thou hast given him a son who sits upon his throne, as it is this day.

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