Gittin 59 - For peaceful co-existence
Seven people are called to read the Torah in the synagogue on Shabbat, and the first one should be the most learned. This law, however ancient and just, could lead to quarrels, and a new rule was adopted: the first one to read is a Kohen, and following him is a Levi. Afterward, regular "Israel" Jews are called. In this way, people don't argue, and peace prevails.
A similar law was established for peace in society: if fish is caught in one's net, technically, it does not belong to the net owner because - if he does not hold the net - he has not acquired it in any of the accepted ways. Nevertheless, the Sages gave him ownership, and now anyone else who takes the fish from the net is considered to be stealing it. Another law: gleanings in the field in Israel are left for the Jewish poor. Yet the Sages accepted the rule that any poor who comes to collect them is permitted to do so - to prevent strife.
