'Do You Not Know' in the Bible

Your boasting [over the supposed spirituality of your church] is not good [indeed, it is vulgar and inappropriate]. Do you not know that [just] a little leaven ferments the whole batch [of dough, just as a little sin corrupts a person or an entire church]?

Do you not know that the saints (God’s people) will [one day] judge the world? If the world is to be judged by you, are you not competent to try trivial (insignificant, petty) cases?

Do you not know that we [believers] will judge angels? How much more then [as to] matters of this life?

Do you not know that the unrighteous will not inherit or have any share in the kingdom of God? Do not be deceived; neither the sexually immoral, nor idolaters, nor adulterers, nor effeminate [by perversion], nor those who participate in homosexuality,

Do you not know that the one who joins himself to a prostitute is one body with her? For He says, “The two shall be one flesh.”

Do you not know that your body is a temple of the Holy Spirit who is within you, whom you have [received as a gift] from God, and that you are not your own [property]?

Do you not know that those who officiate in the sacred services of the temple eat from the temple [offerings of meat and bread] and those who regularly attend the altar have their share from the [offerings brought to the] altar?

Do you not know that in a race all the runners run [their very best to win], but only one receives the prize? Run [your race] in such a way that you may seize the prize and make it yours!
