Listen to my excellent words; all I tell you is right.

Do not use harmful words, but only helpful words, the kind that build up and provide what is needed, so that what you say will do good to those who hear you.

Nor is it fitting for you to use language which is obscene, profane, or vulgar. Rather you should give thanks to God.

Pray, then, that I may speak, as I should, in such a way as to make it clear.

All of us often make mistakes. But if a person never makes a mistake in what he says, he is perfect and is also able to control his whole being.
