'Justly' in the Bible

And we know that the judgment of God falls justly and in accordance with truth on those who practice such things.

He will pay back to each person according to his deeds [justly, as his deeds deserve]:

And why not say, (as some slanderously report and claim that we teach) “Let us do evil so that good may come of it”? Their condemnation [by God] is just.
