The term "Kohen Gadol" refers to the High Priest in ancient Judaism, a key religious figure responsible for performing sacred rituals and maintaining the spiritual well-being of the Israelite community. The Kohen Gadol held a unique position, serving in the Temple in Jerusalem and offering sacrifices, especially on the Day of Atonement, known as Yom Kippur. The Kohen Gadol wore special garments, including a breastplate and a robe, symbolizing his authority and connection to God. This role was hereditary, passed down through the lineage of Aaron, the brother of Moses. The position of Kohen Gadol was central to the religious practices and governance of ancient Israelite society.
