Melchizedek's Kingship

As Abraham returned from his victory over the eastern kings, he encountered the mysterious Melchizedek, “king of Salem” (Jerusalem), who was designated as both a king and priest. Abraham paid “tithes” to the monarch and, in turn, was blessed by him. The New Testament makes Melchizedek a symbol of our king and priest, Jesus Christ (Hebrews 7:15). But the writer of the book of Hebrews makes a curious statement regarding Melchizedek. He says that the ancient ruler was “without father, without mother, without genealogy” (7:3).

Numerous speculations have surrounded this allusion. Origen, an ancient writer (A.D. 185-253) imagined that Melchizedek was an angel. Hierakas, toward the end of the 3rd century A.D., thought that he was a temporary incarnation of the Holy Spirit. Some even have suggested that he was the pre-incarnate Logos (Christ, as depicted in John 1:1,14)—a concept contradicted by Hebrews 7:3, which notes that the king was merely “like unto” the Son of God.

Archaeology has shed light on the enigmatic expression “without father, without mother, etc.” A.H. Sayce, who served as professor of Assyriology at Oxford, called attention to an inscription from the famous Tell el-Amarna tablets (discovered in 1887 in Egypt). These tablets describe the conditions of Syria and Palestine about 1400-1360 B.C.

Several of the Tell el-Amarna tablets are letters written to the Pharaoh by Ebed-tob...the king of Uru-Salim [Jerusalem], who begs for help against his enemies. He tells the Pharaoh that he was not like the other Egyptian governors in Palestine, nor had he received a crown by inheritance from his father or mother; it had been conferred on him by “the Mighty King...” (1906, 3:335).

So, observing the similarity of language, we conclude that Melchizedek’s kingship/priesthood had not been derived genealogically; He had received his commission directly from God Himself. Indeed, as the Scriptures affirm, his was an appointment “of God Most High” (Genesis 14:18). Accordingly, by way of analogy, we are forced to affirm that the current reign/priesthood of our Lord is a direct and divinely authored administration. We are grateful to archaeology for this bit of assistance in understanding what otherwise might be perceived as an obscure reference.
