2 Thessalonians 3:2-3, 6

And pray that we may be delivered from wicked and evil people, for not everyone has faith. But the Lord is faithful, and he will strengthen you and protect you from the evil one.

In the name of the Lord Jesus Christ, we command you, brothers and sisters, to keep away from every believer who is idle and disruptive and does not live according to the teaching you received from us.
