A dayan is a traditional Jewish religious judge who is part of a rabbinical court, known as a beit din. The dayan's role is to interpret Jewish law, or halacha, and resolve disputes among individuals or communities. They are often called upon to make decisions on matters such as marriage, divorce, and business ethics.
Dayanim are typically well-versed in Jewish texts, including the Talmud and various legal codes. Their authority is recognized within the Jewish community, and their rulings can have significant implications for the lives of those involved. The position of dayan is respected and requires extensive training and knowledge.
