19 Understand this, my dear brothers and sisters! Let every person be quick to listen, slow to speak, slow to anger. 20 For human anger does not accomplish God’s righteousness. 21 So put away all filth and evil excess and humbly welcome the message implanted within you, which is able to save your souls. 22 But be sure you live out the message and do not merely listen to it and so deceive yourselves. 23 For if someone merely listens to the message and does not live it out, he is like someone who gazes at his own face in a mirror. 24 For he gazes at himself and then goes out and immediately forgets what sort of person he was. 25 But the one who peers into the perfect law of liberty and fixes his attention there, and does not become a forgetful listener but one who lives it out—he will be blessed in what he does. 26 If someone thinks he is religious yet does not bridle his tongue, and so deceives his heart, his religion is futile.

15 Shammai used to say: make your [study of the] Torah a fixed practice; speak little, but do much; and receive all men with a pleasant countenance. 16 Rabban Gamaliel used to say: appoint for thyself a teacher, avoid doubt, and do not make a habit of tithing by guesswork. 17 Shimon, his son, used to say: all my days I grew up among the sages, and I have found nothing better for a person than silence. Study is not the most important thing, but actions; whoever indulges in too many words brings about sin.
