The Greek hierus and its various forms that are typically translated as “priest” in English (itself deriving from Latin “presbyter” — “elder”) is often translated with a consideration of existing religious traditions. (Click or tap for details)
Bratcher / Nida (1961) say this:
However, rather than borrow local names for priests, some of which have unwanted connotations, a number of translations have employed descriptive phrases based on certain functions: (1) those describing a ceremonial activity: Pamona uses “tadu,” the priestess who recites the litanies in which she describes her journey to the upper or under-world to fetch life-spirit for sick people, animals or plants; Batak Toba uses the Arabic “malim,” “Muslim religious teacher;” “one who presents man’s sacrifice to God” (Bambara, Eastern Maninkakan), “one who presents sacrifices” (Baoulé, Navajo), “one who takes the name of the sacrifice” (Kpelle), and “to make a sacrifice go out” (Hausa); (2) those describing an intermediary function: “one who speaks to God” (Shipibo-Conibo) and “spokesman of the people before God” (Tabasco Chontal).
The [local] cult of Poro used to be an all-encompassing religious system that essentially governed all areas of life. (…) For ‘priest’ the term “poro father” would at first seem to be a natural choice. However, several priests of the old cult are still living. Although they no longer function primarily as priests of the old system they still have a substantial influence on the community, and there would be more than a chance that the unqualified term would (in some contexts particularly) be equated with the priest of the poro cult. We learned, then, that the poro fathers would sometimes be called “knife men” in relation to their sacrificial work. The panel was pleased to apply this term to the Jewish priest, and the Christian community has adopted it fully. [Mark 1:44, for instance, now] reads: “You must definitely not tell any man of this. But you go show your body to the knife man and do what Moses said about a sacrifice concerning your being healed, and the cause (base of this) will be apparent.”
Bocheachary — The use of this new construction meaning “priest” is maintained to translate the Greek word hiereus. The term “lauk sang” used in the old version actually means a “Buddhist monk,” and is felt to be theologically misleading. The Khmer considers the Buddhist monk as a “paddy field of merits,” a reserve of merits to be shared with other people. So a Khmer reader would find unthinkable that the lauk sang in the Bible killed animals, the gravest sin for a Buddhist; and what a scandal it would be to say that a lauk sang was married, had children, and drank wine.
