Your question solicits references of priest occur in the bible, but then conveniently cherry pick, while leaving out other canonized, biblical scripture, ever pretending that you're covering the waterfront, so to speak, if not being exhaustive.
Are you denying biblical canon? Do you burden biblical questions with other, extra-biblical tradition? What sense does that make?

It seems to me that you made no representation other than that the word priest appears in 1 Peter.
Also, your swipe at Eucharistic Vestments points to an agenda.
