(6) For when the Gentiles, which have (i) not the law, do by (k) nature the things contained in the law, these, having not the law, are a law unto themselves:
(6) He prevents an objection which might be made by the Gentiles, who even though they do not have the law of Moses, yet they have no reason why they may excuse their wickedness, in that they have something written in their hearts instead of a law, as men do who forbid and punish some things as wicked, and command and commend other things as good.
(i) Not that they are without any law, but rather the law of the Jews.
(k) Command honest things, and forbid dishonest.
