'Writing' in the Bible

I'm not writing this to make you feel ashamed, but to warn you as my dear children.

But now I am writing to you to stop associating with any so-called brother if he is sexually immoral, greedy, an idolater, a slanderer, a drunk, or a robber. You must even stop eating with someone like that.

But I have not used any of these rights, and I'm not writing this so that they may be applied in my case. I would rather die than let anyone deprive me of my reason for boasting.

If anyone thinks he is a prophet or a spiritual person, he must acknowledge that what I am writing to you is the Lord's command.

I, Paul, am writing this greeting with my own hand.
