I beseech you, brethren: mark them which cause division, and give occasions of evil contrary to the doctrine which ye have learned; and avoid them.

but now I write unto you that ye company not together. If any that is called a brother, be a fornicator, or covetous, or a worshipper of images, either a railer, either a drunkard, or an extortioner: with him that is such see that ye eat not.

I have not dwelt with vain persons; neither will I have fellowship with the deceitful.

Set yourselves therefore at large, and bear not a stranger's yoke with the unbelievers. For what fellowship hath righteousness with unrighteousness? What company hath light with darkness?

and when the LORD thy God hath set them before thee that thou shouldest smite them: see that thou utterly destroy them and make no covenant with them nor have compassion on them.

confess now therefore unto the LORD God of your fathers, and do his pleasure, and separate yourselves from the people of the land, and from the strange wives."

And he spake unto the congregation, saying, "Depart from the tents of these wicked men and touch nothing of theirs: lest ye perish in all their sins."

My son, consent not unto sinners,

See that thou meddle not with a fool; and do as though thou hadst no knowledge.

We require you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh inordinately, and not after the institution which ye received of us.
