44 But I say to you, love your enemy and pray for those who persecute you, 45 so that you may be like your Father in heaven, since he causes the sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. 46 For if you love those who love you, what reward do you have? Even the tax collectors do the same, don’t they? 47 And if you only greet your brothers, what more do you do? Even the Gentiles do the same, don’t they? 48 So then, be perfect, as your heavenly Father is perfect.

13 He [also] used to say: one who makes his name great causes his name to be destroyed; one who does not add [to his knowledge] causes [it] to cease; one who does not study [the Torah] deserves death; one who makes [unworthy] use of the crown [of learning] shall pass away. 14 He [also] used to say: If I am not for myself, who is for me? But if I am for my own self [only], what am I? And if not now, when? 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.
