Who served as priests in On?

I. Historical Context of On

On, also known as Heliopolis (meaning “City of the Sun” in Greek), was an ancient city in Lower Egypt. Biblically, the name “On” appears in Genesis and Ezekiel (Genesis 41:45; Ezekiel 30:17), with its residents and priests prominently mentioned during Joseph’s time. Situated northeast of modern-day Cairo, On served as a major religious center, especially known for the worship of the sun deity revered by the Egyptians. Archaeological findings in the region point to its significance as one of Egypt’s oldest cities.

II. References in Scripture

Scripture directly mentions On in contexts tied to Joseph, who rose to prominence in Egypt. Pharaoh gave Joseph Asenath, the daughter of a priest of On, as his wife:

• “Pharaoh gave Joseph the name Zaphenath-paneah, and he gave him Asenath daughter of Potiphera, priest of On, to be his wife…” (Genesis 41:45)

Later, Scripture records the sons born to Joseph and Asenath, again noting the family’s priestly heritage:

• “Before the years of famine arrived, two sons were born to Joseph by Asenath daughter of Potiphera, priest of On.” (Genesis 41:50)

In these verses, On is directly tied to the priestly class through Asenath’s father, Potiphera.

III. The Role of Priests in On

The priests of On served primarily in worship of the Egyptian sun god. The city’s identity as a center for this cultic activity meant its priesthood held considerable influence, both religiously and politically. Egyptian history and archaeological evidence highlight the extensive temple complexes in On, with priests who oversaw rituals, offered sacrifices, and instructed adherents in reverence of their deity.

From the biblical perspective, the priesthood in On is illustrated through Potiphera. His name is commonly interpreted as “He Whom Ra (or Re) Gave,” reflecting his devotion to the local deity. The Bible does not provide a complete roster of every priest who served in On, yet Potiphera is singled out because of his connection to Joseph, one of the central figures in Genesis.

IV. Potiphera: Priest of On

1. Background and Name

Potiphera, mentioned by name in Genesis 41:45 and 41:50, was the father of Asenath. The name “Potiphera” carries connotations linked to the Egyptian sun god, hinting at his high standing in the religious life of On.

2. Family Ties to Joseph

Joseph married Asenath, uniting the Israelite patriarchal narrative with the priestly family of On. This connection elevated Joseph’s standing in Egyptian society and fulfilled God’s providential plan to preserve Israel through the ensuing years of famine.

V. Other Priests and the Egyptian Cultic System

Outside the biblical narrative, historical and extrabiblical documents (including inscriptions, temple records, and writings from Greek historians who interacted with ancient Egypt) reinforce that the city’s priests came from a hereditary line. Often, priestly roles in Ancient Egypt passed from father to son. On’s priests would have overseen significant rituals connected with the worship of Ra, maintaining altars, reciting liturgies, and ensuring the continuation of religious festivals.

Though these records do not specifically name every priest of On during Joseph’s era, they do confirm the prominence of On’s temple system and its influential priestly class. Artifacts, such as temple carvings from Heliopolis, further attest to a well-organized hierarchy that placed the high priest at the apex of power.

VI. The Intersection of Biblical and Historical Evidence

Biblical manuscripts, supported by numerous reliable copies and consistent textual transmission, give a trustworthy account of On’s role in Joseph’s life. Archaeological discoveries in ancient Heliopolis (large obelisks, temple remnants, and inscriptions) corroborate the city’s existence and its religious importance. These findings align with the Genesis narrative of Joseph’s integration into Egyptian society through marriage into the priestly family.

VII. Summary and Key Takeaways

1. City of On (Heliopolis): A major ancient Egyptian religious center.

2. Priests of On: They served the sun god and held significant cultural authority.

3. Potiphera: Named explicitly in Scripture as an example of a priest in On (Genesis 41:45, 50).

4. Joseph’s Connection: His marriage to Asenath, daughter of Potiphera, grafted him into the Egyptian priestly household.

5. Historical Support: Archaeological and extrabiblical sources confirm On’s priesthood as a powerful and enduring institution.

Thus, those identified by Scripture (most notably Potiphera) served as priests in On, signifying that On’s priestly class was recognized for their profound religious influence. The account illustrates how biblical truth and archaeology unite in affirming the existence of On and the role its priesthood played in Egypt’s ancient narrative.
