The Hebrew word "kohen" primarily denotes a priest, an individual authorized to perform sacred rites and mediate between God and people. This role was particularly significant in ancient Israel, where priests were central to the religious life of the community. They were responsible for offering sacrifices, maintaining the purity of the sanctuary, and instructing the people in God’s law. The priesthood was hereditary, typically passed down through the line of Aaron, ensuring a continuous lineage of those dedicated to divine service. Their duties involved not only cultic acts but also maintaining the spiritual and moral well-being of the nation. They had an important teaching function as well, interpreting the law and providing guidance to the people regarding its application in their daily lives. In the Old Testament, the priest symbolized access to God and the means of atonement for sin.

The semantic range of "kohen" is quite focused, primarily referring to this religious office. However, it can occasionally extend to individuals who, while not of the traditional priestly lineage, perform priestly functions, as seen with some non-Israelite priests mentioned in the biblical narrative. The theological weight of "kohen" is immense, as the institution of the priesthood was divinely ordained and integral to the covenant relationship between God and Israel. The priests were entrusted with the sacred rituals that maintained ritual purity and offered a path for the atonement of communal and individual sin. Their activities were crucial for maintaining the holiness of the people in the sight of God.

The New Testament presents Jesus Christ as the ultimate High Priest, who offers a perfect and final sacrifice for sins, thus fulfilling and transcending the Old Testament priestly system. His priesthood is of a different order, not according to the Levitical law, but after the order of Melchizedek (Hebrews 7). This new covenant understanding transforms the concept of priesthood, shifting from a hereditary, ritualistic office to a spiritual reality centered on Christ's once-for-all sacrifice. The New Testament also speaks of all believers as a "royal priesthood" (1 Peter 2:9), implying a direct access to God and a calling to offer spiritual sacrifices of praise and service. This concept expands the priestly function beyond a select few to the entire community of faith. The Old Testament "kohen," therefore, lays the foundational understanding for these developed theological themes in the New Testament.
