'Righteousness' in the Bible

Then Solomon said, “You have shown great lovingkindness to Your servant David my father, according as he walked before You in truth and righteousness and uprightness of heart toward You; and You have reserved for him this great lovingkindness, that You have given him a son to sit on his throne, as it is this day.

then hear in heaven and act and judge Your servants, condemning the wicked by bringing his way on his own head and justifying the righteous by giving him according to his righteousness.

Blessed be the Lord your God who delighted in you to set you on the throne of Israel; because the Lord loved Israel forever, therefore He made you king, to do justice and righteousness.”
