25 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made ruler over the heavens;
26 And not as those high priests who offered up sacrifice daily, first for their own sins, and then for the sins of the people; for he needeth not offer sacrifice for his own sins, for he knew no sins; but for the sins of the people. And this he did once, when he offered up himself.
27 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 forevermore.
Hebrews 8 Intro: Of the priesthood -- The new covenant.
1 Now of the things which we have spoken this is the sum; we have such a high priest, who is set on the right hand of the throne of the Majesty in the heavens;
2 A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
3 For every high priest is ordained to offer gifts and sacrifices; wherefore it is of necessity that this man have somewhat also to offer.
4 Therefore while he was on the earth, he offered for a sacrifice his own life for the sins of the people. Now every priest under the law, must needs offer gifts, or sacrifices, according to the law.
5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle; for, See, saith he, that thou make all things according to the pattern showed to thee in the mount.
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
