17 Now I urge you, brothers, to keep your eye on those who create divisions and causes for stumbling contrary to the teaching that you have learned, and avoid them.+ 18 For men of that sort are slaves, not of our Lord Christ, but of their own appetites,* and by smooth talk and flattering speech they seduce the hearts of unsuspecting ones.

2 However, there also came to be false prophets among the people, as there will also be false teachers among you.+ These will quietly bring in destructive sects, and they will even disown the owner who bought them,+ bringing speedy destruction upon themselves.
