By the eternal priesthood of Christ the Levitical priesthood of Aaron is abolished.
Hebrews 8:1 Now a summary of the things of which we are speaking [is], We have such a one high priest who has sat down on [the] right hand of the throne of the greatness in the heavens; Hebrews 8:2 minister of the holy places and of the true tabernacle, which the Lord has pitched, [and] not man. Hebrews 8:3 For every high priest is constituted for the offering both of gifts and sacrifices; whence it is needful that this one also should have something which he may offer. Hebrews 8:4 If then indeed he were upon earth, he would not even be a priest, there being those who offer the gifts according to the law, Hebrews 8:5 (who serve the representation and shadow of heavenly things, according as Moses was oracularly told [when] about to make the tabernacle; for See, saith He, that thou make all things according to the pattern which has been shewn to thee in the mountain.) Hebrews 8:6 But now he has got a more excellent ministry, by so much as he is mediator of a better covenant, which is established on the footing of better promises.
And the temporal Covenant with the fathers, by the eternal Covenant of the Gospel.
Hebrews 8:7 For if that first was faultless, place had not been sought for a second. Hebrews 8:8 For finding fault, he says to them, Behold, days come, saith the Lord, and I will consummate a new covenant as regards the house of Israel, and as regards the house of Juda; Hebrews 8:9 not according to the covenant which I made to their fathers in [the] day of my taking their hand to lead them out of the land of Egypt; because *they* did not continue in my covenant, and *I* did not regard them, saith [the] Lord. Hebrews 8:10 Because this [is] the covenant that I will covenant to the house of Israel after those days, saith the Lord: Giving my laws into their mind, I will write them also upon their hearts; and I will be to them for God, and *they* shall be to me for people. Hebrews 8:11 And they shall not teach each his fellow-citizen, and each his brother, saying, Know the Lord; because all shall know me in themselves, from [the] little one [among them] unto [the] great among them. Hebrews 8:12 Because I will be merciful to their unrighteousnesses, and their sins and their lawlessnesses I will never remember any more. Hebrews 8:13 In that he says New, he has made the first old; but that which grows old and aged [is] near disappearing.
