10 If anyone comes to you not having this teaching, do not take him into your house or give him words of love:
But even if we, or an angel from heaven, were to be a preacher to you of good news other than that which we have given you, let there be a curse on him. As we have said before, so say I now again, If any man is a preacher to you of any good news other than that which has been given to you, let there be a curse on him.
Now, it is my desire, brothers, that you will take note of those who are causing division and trouble among you, quite against the teaching which was given to you: and keep away from them. For such people are not servants of the Lord Christ, but of their stomachs; and by their smooth and well-said words the hearts of those who have no knowledge of evil are tricked.
