"Do not be yoked together with unbelievers." I was just talking to our pastor about this and apparently the context was of worshiping idols; we shouldn't worship other Gods along with unbelievers. In fact, Paul suggests in an earlier letter that we should have friendships with people who aren't Christians. "If one of the unbelievers invites you and you want to go, eat anything that is set before you without asking questions for conscience' sake."
