Rabban Gamliel used to say: Make a teacher for yourself and remove yourself from doubt, and do not be wont to tithe by es-timation.

Shimon his son says: All my days I grew up among the Sages, and I did not find [some- thing as] good for a person other than silence. And study is not the main [objective], rather action [is]. And whoever talks excessively brings sin.

Rabban Shimon ben Gamliel says: The world stands on three things: upon justice, upon truth, and upon peace, as it is stated: Judge [with] truth, justice [and] peace in your gates.

Rebbi says: Which is the proper path that a person should choose for himself? Whatever [path] is a benefit to himself and earns him the praise of fellow men. Be as scrupulous in performing a “minor” mitzvah as in a “major” one, for you do not know the reward given for the [respective] mitzvos. Calculate the cost of a mitzvah against its reward, and the reward of a sin against its cost. Consider three things, and you will not come into the grip of sin: Know what is above you: a watchful Eye, an attentive Ear, and all your deeds are recorded in a Book.
