'Speech' in the Bible

And I say this to the end that no one may delude you by persuasive speech.

But now you must also get rid of anger, wrath, malice, slander, obscene speech, and all such sins.

And whatever you do, whether by speech or action, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.

Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.
