2 Thessalonians 3:13-17

But as for you, brothers and sisters, do not grow weary of doing good.

If anyone does not obey our instruction in this letter, take special note of that person so as not to associate with him, so that he will be put to shame.

And yet do not regard that person as an enemy, but admonish that one as a brother or sister.

Now may the Lord of peace Himself continually grant you peace in every circumstance. The Lord be with you all!

I, Paul, write this greeting with my own hand, and this is a distinguishing mark in every letter; this is the way I write.
