Salmos 38

Salmos 38:14

You should walk as one that is deaf and dumb and blind, so that, putting aside the contemplation of him who has been rightly chosen by you as your model of perfection, you should be like one who is blind and not see any of those things that you find to be unedifying. Nor should you be influenced by the authority or fashion of those who do these things and give yourself up to what is worse and what you formerly condemned. If you hear anyone disobedient or insubordinate or disparaging another or doing anything different from what was taught to you, you should not go wrong and be led astray by such an example to imitate him, but, "like one who is deaf," as if you had never heard it, you should pass it all by. — INSTITUTES 4:41
