Mishna, Pirkei Avot 1:18
משנה מסכת אבות פרק א:יח
רבן שמעון בן גמליאל אומר על שלשה דברים העולם עומד על הדין ועל האמת ועל השלום שנאמר (זכריה ח) אמת ומשפט שלום שפטו בשעריכם:
Rabbi Shimon the son of Gamliel would say: By three things is the world sustained: law, truth and peace. As is stated (Zachariah 8:16), "Truth, and a judgment of peace, you should administer at your [city] gates.'' [Translation by chabad.org]

Suggested Discussion Questions:

1. How do these three things sustain the world? Do they do so independently?

2. How is peace created? How is peace sustained? Why are law and truth necessary to achieve this?

Time Period: Rabbinic (Maccabees through the Talmud)
