Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks in rebellion, and not after the tradition which they received from us.
that ye withdraw yourselves from every brother that walketh disorderly: The phrase "withdraw yourselves" (stellomai) has a meaty meaning "to bring together, contract, shorten...to diminish, check, cause to cease; to cease to exist,...to remove one’s self, withdraw one’s self, to depart,...to abstain from familiar intercourse with one" (Thayer 587-1-4724). The phrase "that walketh" (peripateo) means "to regulate one’s life, to conduct one’s self (Thayer 83-1-813)." This command is given to the entire congregation.
