You left out the third order. The Apostles also ordained "presbyterois" (also translated into English as 'presbyters' or 'elders'). These are the priests, for they offered the Eucharistic sacrifice to God.

They are referred to loosely as pastors, but not as priests, per se. They may have blessed and poured more often than not, but there is no Scriptural ordination of calling elders a priestly class, with sole responsibility to serve our holy communion of the New Covenant.
Remember that in the original Last Supper, the drinkers all "passed the cup" one to another. This specifically recognizes Jesus as our singular High Priests, while all the rest of us priests are peers at the foot of both the cross and the throne.
