2 Thessalonians 3:4-6

We have confidence in the Lord concerning you, that you are doing and will continue to do what we command. May the Lord direct your hearts into the love of God and into the steadfastness of Christ. Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from every brother who leads an unruly life and not according to the tradition which you received from us.
