Kohanim are members of the priestly class in Judaism, traditionally believed to be descendants of Aaron, the brother of Moses. They have specific religious duties, particularly in the context of the Temple in Jerusalem, where they performed sacrifices and other rituals. Today, Kohanim are recognized during certain prayers and blessings in synagogues. In Jewish law, Kohanim have unique roles and restrictions, such as not being allowed to come into contact with the dead, except for close relatives. They also receive special honors during religious services, such as being called first to the Torah.
