13 Brothers and sisters, don't ever get tired of doing the right thing.
14 Keep an eye on anyone who doesn't obey the directions in our letter. Watch that person closely. Have nothing to do with him. Then he will feel ashamed.
15 But don't think of him as an enemy. Instead, warn him as a brother or sister.
16 May the Lord who gives peace give you peace at all times and in every way. May the Lord be with all of you.
17 I, Paul, write this greeting in my own handwriting. That's how I prove that I am the author of all my letters. I always do it that way.
