Those who formerly became priests took their office without an oath, but he became a priest with an oath through the One who said to him, "The Lord has sworn and will not change his mind, 'You are a priest forever.'"

For every high priest is appointed to offer both gifts and sacrifices; and so it is necessary for this priest also to have something to offer.

Now if he were on earth, he would not be a priest at all, since there are priests who offer the gifts according to the law.
