Now I urge you, brothers and sisters, to keep your eye on those who are causing divisions and stumbling blocks, contrary to the teaching that you learned. Turn away from them.
Now we command you, brothers and sisters, in the name of our Lord Yeshua the Messiah, to keep away from every brother who behaves irresponsibly and not according to the tradition they received from us.
See that no one takes you captive through philosophy and empty deception, according to the tradition of men and the basic principles of the world rather than Messiah.
Now this issue came up because of false brothers secretly brought in (who slipped in to spy out our freedom in Messiah, in order to bring us into bondage).
They left us, but they didn’t really belong to us. If they had belonged to us, they would have remained with us. But they left us so it became clear that none of them belongs to us.
But if he refuses to listen to them, tell it to Messiah’s community. And if he refuses to listen even to Messiah’s community, let him be to you as a pagan and a tax collector.
