Because King James, and all Protestant translators superstitiously avoided it. Still "priest" derives from "presbyteros" and has the same meaning.
See 1 Timothy 5:1, 4:14.
I stand corrected as to ieros, we do see it in 1 Peter as "ierateuma", priesthood.
Ever actually study the translation of the King James Bible? The men who did so were quite competent and careful scholars - and King James wasn't one of them.
Actually, ever study King James? He wasn't exactly unfriendly to Catholics, so I don't know why you would say he was avoiding translating presbuteros "priest"
The verse in Timothy is translated ELDER, and such translation makes perfect sense since the verse reads
1 Timothy 5
1Rebuke not an elder, but intreat him as a father; and the younger men as brethren;
The other verse reads: 14Neglect not the gift that is in thee, which was given thee by prophecy, with the laying on of the hands of the presbytery.
The verse before that by the way reads: 13Till I come, give attendance to reading, to exhortation, to doctrine.
Actually, the whole chapter is meaty.
It starts out this way:
1 Timothy 4
1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2Speaking lies in hypocrisy; having their conscience seared with a hot iron;
3Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
I don't know of any protestants who forbid people to marry or abstain from meats.
