Now I beg you, brothers, look out for those who are causing the divisions and occasions of stumbling, contrary to the doctrine which you learned, and turn away from them.
Give no occasions for stumbling, either to Jews, or to Greeks, or to the assembly of God;
You became imitators of us, and of the Lord, having received the word in much affliction, with joy of the Holy Spirit,
For you know how you ought to imitate us. For we didn't behave ourselves rebelliously among you,
If any man doesn't obey our word in this letter, note that man, that you have no company with him, to the end that he may be ashamed.
Remember your leaders, men who spoke to you the word of God, and considering the results of their conduct, imitate their faith.
