Do not [try to] pay back a wrong done to you by doing something wrong to the other person. Think about how to live honorably in front of all people.

Do not take revenge on someone who has wronged you, but leave it up to God's wrath [to take care of it], for it is written [Deut. 22:35], "The Lord says, I will pay people back [for doing wrong] because taking revenge belongs to me."

So, whoever you are, you people do not have any excuse for judging people [Note: At this point Paul begins addressing the Jews. See verse 17]. For in a matter where you judge someone else [to be wrong] you [actually] condemn yourselves, because you are practicing the same things [you condemn them for doing].

For [our] rulers are not a threat to [the person doing] a good deed, but to [the person doing] an evil one. So, do you want to avoid having to be afraid of the authorities? Then do what is good and you will be commended by them [generally].

In doing this [i.e., practicing some of the requirements of the law of Moses], they demonstrate that these requirements are written in their hearts. Their conscience tells them this, and their thoughts alternately accuse them [of wrongdoing], or else endorse them [for doing right]).
