7:27. Who needeth not daily (as the other priests) to offer sacrifices, first for his own sins, and then for the people's: for this he did once, in offering himself.

7:28. For the law maketh men priests, who have infirmity: but the word of the oath (which was since the law) the Son who is perfected for evermore.

Hebrews Chapter 8

More of the excellence of the priesthood of Christ and of the New
Testament.

8:1. Now of the things which we have spoken, this is the sum: We have such an high priest who is set on the right hand of the throne of majesty in the heavens,

8:2. A minister of the holies and of the true tabernacle, which the Lord hath pitched, and not man.

The holies. . .That is, the sanctuary.

8:3. For every high priest is appointed to offer gifts and sacrifices: wherefore it is necessary that he also should have some thing to offer.

8:4. If then he were on earth, he would not be a priest: seeing that there would be others to offer gifts according to the law.

If then he were on earth, etc. . .That is, if he were not of a higher condition than the Levitical order of earthly priests, and had not another kind of sacrifice to offer, he should be excluded by them from the priesthood, and its functions, which by the law were appropriated to their tribe.
