These two verses help us to see that who we hang around with is who we will imitate if we stay around them long enough. if we hang around people who use bad language we will begin to use the same language. If we hang with someone who commits murder we are guilty by association. Fellowship has a tendency to teach you the evil ways of the one you fellowship with. We are told not to be unequally with those of unbelief. A man or woman will pick up the habits of the people they hang around with whether good or bad. So these verses let us know to surround ourselves with Godly people if we want to be a Godly person.
