'Whose' in the Bible

But actually, I have written to you not to associate with any so-called [Christian] brother if he is sexually immoral or greedy, or is an idolater [devoted to anything that takes the place of God], or is a reviler [who insults or slanders or otherwise verbally abuses others], or is a drunkard or a swindler—you must not so much as eat with such a person.

Now these things happened to them as an example and warning [to us]; they were written for our instruction [to admonish and equip us], upon whom the ends of the ages have come.
