He utters empty words; he utters sound without meaning. [ Virgil ]

His promises are lighter than the breath that utters them. [ Proverb ]

Surely he is not a fool that hath unwise thoughts, but he that utters them. [ Bishop Hall ]

Whatever may be the means, or whatever the more immediate end of any kind of art, all of it that is good agrees in this, that it is the expression of one soul talking to another, and is precious according to the greatness of the soul that utters it. [ Ruskin ]

Exaggeration is neither thoughtful, wise, nor safe; it is a proof of the weakness of the understanding, or the want of discernment of him that utters it, so that even when he speaks the truth, he soon finds it is received with large discount, or utter unbelief. [ W. B. Kinney ]
