'Certainly Not' in the Bible

certainly not meaning the fornicators of this world, or the covetous and extortioners, or idolaters; for to do this ye must go out of the world.

You know that your bodies belong to the Messiah, don't you? Should I take what belongs to the Messiah and unite them with a prostitute? Certainly not!

[Certainly not!] But I am saying that the Gentile sacrifices are [really] offered to evil spirits and not to God. And I do not want you to have fellowship with evil spirits.

But a man should certainly not cover his [physical] head [i.e., with "something hanging down," such as long hair or a cloth shawl. See verse 4], since he is the image and glory of God. But the woman [i.e., his wife] is the glory of the man [i.e., her husband].

What? have you not houses to take your meals in? or have you no respect for the church of God, putting the poor to shame? What am I to say to you? am I to give you praise? certainly not.
