'Righteousness' in the Bible

then hear thou from heaven, and do, and judge thy servants, requiting 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 his throne, to be king for Jehovah thy God: because thy God loved Israel, to establish them for ever, therefore made he thee king over them, to do justice and righteousness.
