A Kohen is a member of the priestly class in Judaism, traditionally believed to be descendants of Aaron, the brother of Moses. Kohanim, the plural form, have specific religious duties and privileges, including performing certain rituals in the synagogue and the Temple. They are also responsible for blessing the congregation during specific prayers. In Jewish law, Kohanim are subject to unique rules, such as restrictions on marrying certain individuals and requirements for ritual purity. The role of a Kohen is significant in Jewish tradition, symbolizing a connection to the ancient Temple in Jerusalem and the spiritual leadership of the Jewish people.
