So that, my beloved brothers, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not without fruit in the Lord.
Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks disorderly, and not after the teaching which he received from us.
Having made all haste to write to you about the common salvation, beloved, I had need to write to you to exhort you to contend earnestly for the faith once delivered to the saints.
