'Righteousness' in the Bible

but in every nation he that feareth him, and worketh righteousness, is acceptable to him.

and said, O full of all guile and all villany, thou son of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?

inasmuch as he hath appointed a day in which he will judge the world in righteousness by the man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.

And as he reasoned of righteousness, and self-control, and the judgment to come, Felix was terrified, and answered, Go thy way for this time; and when I have a convenient season, I will call thee unto me.
