'Priests' in the Bible

None of this happened without an oath. For others became priests without an oath,

(For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)

And they truly were many priests, because they were not suffered to continue by reason of death:

Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.

For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.

For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:

Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God.

For, since the Law exhibits only an outline of the blessings to come and not a perfect representation of the things themselves, the priests can never, by repeating the same sacrifices which they continually offer year after year, give complete freedom from sin to those who draw near.

We have an altar from which those priests who are servants in the Tent may not take food.

You, as living stones, are being made into a house of the spirit, a holy order of priests, making those offerings of the spirit which are pleasing to God through Jesus Christ.

But you are a special people, a holy nation, priests and kings, a people given up completely to God, so that you may make clear the virtues of him who took you out of the dark into the light of heaven.

And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.

And hast made us unto our God kings and priests: and we shall reign on the earth.

Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
