### Core Meaning & Semantic Range
The Greek word **hierōsýnē**, represented by `{{G2420}}`, refers to **the priestly office**, or **priesthood**. It appears **4 times** across **4 unique verses** in the Bible. The term's root in sacredness points to the role and function of the priesthood within God's law.
### Biblical Occurrences & Contextual Analysis
All occurrences of `{{G2420}}` are in the book of Hebrews and are used to contrast the old priesthood with the new one in Christ. It is used to describe the **Levitical priesthood**, through which the law was given to the people but which could not bring perfection [[Hebrews 7:11]]. The text establishes that Jesus descended from Judah, a tribe about which Moses said nothing concerning the **priesthood** [[Hebrews 7:14]]. Because of this, the **priesthood** had to be changed [[Hebrews 7:12]], leading to Christ's unchangeable **priesthood** [[Hebrews 7:24]].
### Related Words & Concepts
Several related words expand upon the concept of the priestly office:
* `{{G2409}}` **hiereús** (a priest): This term identifies the individual holding the priestly office. It is used to refer to Melchisedec [[Hebrews 7:1]], the priests who ministered daily under the law [[Hebrews 10:11]], and believers who are made kings and **priests** unto God [[Revelation 1:6]].
* `{{G3020}}` **Leuïtikós** (Levitical): This word specifically defines the priesthood associated with the Levites. It is used directly with **priesthood** to form the term "**Levitical** priesthood" [[Hebrews 7:11]], establishing the context for the change in priestly orders.
### Theological Significance
The theological weight of `{{G2420}}` is focused on the transition of covenants.
* **Insufficiency of the Old System:** The term is used to frame the **Levitical priesthood** as a system that could not bring about perfection, thus requiring a new and better hope [[Hebrews 7:11]].
* **A Change in Law and Priesthood:** A central point is that a change in the **priesthood** from the Levitical order to the order of Melchisedec necessitates a change in the law itself [[Hebrews 7:12]].
* **Christ's Eternal Office:** The word culminates in describing Jesus's role, who holds an "unchangeable **priesthood**" because he continues forever [[Hebrews 7:24]], unlike the mortal priests before Him.
### Summary
In summary, `{{G2420}}` is a crucial term for understanding the shift in redemptive history detailed in the book of Hebrews. It is used exclusively to contrast the temporary, insufficient **Levitical priesthood** with the eternal and perfect **priesthood** of Jesus Christ. The word highlights how Christ’s appointment as priest fundamentally changes the law and establishes a permanent means of access to God.
