By the eternal priesthood of Christ the Levitical priesthood of Aaron is abolished.
Hebrews 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 the Majesty in the heavens; Hebrews 8:2 A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man. Hebrews 8:3 For every high priest is ordained to offer gifts and sacrifices: wherefore [it is] of necessity that this man have somewhat also to offer. Hebrews 8:4 For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law: Hebrews 8:5 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 shewed to thee in the mount. Hebrews 8:6 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.
And the temporal Covenant with the fathers, by the eternal Covenant of the Gospel.
Hebrews 8:7 For if that first [covenant] had been faultless, then should no place have been sought for the second. Hebrews 8:8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah: Hebrews 8:9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. Hebrews 8:10 For this [is] the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people: Hebrews 8:11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. Hebrews 8:12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more. Hebrews 8:13 In that he saith, A new [covenant], he hath made the first old. Now that which decayeth and waxeth old [is] ready to vanish away.
