Melchizedek is a biblical figure mentioned in the Book of Genesis. He is described as the king of Salem and a priest of God Most High. Melchizedek meets Abram after a battle and blesses him, receiving a tithe in return. His dual role as both king and priest is significant in biblical tradition. In the New Testament, Melchizedek is referenced in the Book of Hebrews, where he is seen as a type of Christ. The comparison highlights the eternal priesthood of Jesus, suggesting that like Melchizedek, He transcends the traditional Levitical priesthood. This connection emphasizes the spiritual significance of Melchizedek in Christian theology.
