The Ultimate Moses and Aaron

Moses (see Palace Prince To Sinai Shepherd) and Aaron (see Aaron: The Prophet's Prophet) are two of the most famous people, both Levites (as was John the Baptist - see The Prophet Of The Judean Wilderness), of Bible History. They were however much more. Both served as minor portrayals of Jesus Christ, one as a "deliverer" of God's people, the other as a "high priest" through whom atonement for the people's sins was made (just as, moreover, King David also filled a prophetic role of the coming Messiah i.e. Christ was descended from Judah, as was His physical ancestor David, not from Levi, as were Moses and Aaron; see Israelite Monarchy - The Messiah). All of those offices (and far, far more - see Christ The Creator) were held by Christ before Moses, Aaron or David were ever born:

"^7:9 And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham [see Abraham's Journey, The Exodus Prophecy and Circumcision]. ^7:10 For he was yet in the loins of his father, when Melchisedec met him [see Melchizedek: A Portrayal Of Christ and 'Before Abraham Was, I AM']. ^7:11 If therefore perfection were by the Levitical priesthood, for under it the people received the law, what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? ^7:12 For the priesthood being changed, there is made of necessity a change also of the law. ^7:13 For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar.

^7:14 For it is evident that our Lord sprang out of Judah; of which tribe Moses spake nothing concerning priesthood. ^7:15 And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, ^7:16 Who is made, not after the law of a carnal commandment, but after the power of an endless life [see the Fact Finder question below]. ^7:17 For he testifieth, Thou art a priest for ever after the order of Melchisedec." (Hebrews 7:9-17 KJV)

"For they drank of that spiritual Rock that followed them: and that Rock was Christ"

Moses was the Deliverer's prophet (see The Master's Messenger), the leader of God's people as they were all being led by Christ.

"^10:1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea; ^10:2 And were all baptized unto Moses in the cloud and in the sea [see Why Through The Sea?]; ^10:3 And did all eat the same spiritual meat; ^10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ. ^10:5 But with many of them God was not well pleased: for they were overthrown in the wilderness.

^10:6 Now these things were our examples, to the intent we should not lust after evil things, as they also lusted. ^10:7 Neither be ye idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play. ^10:8 Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand. ^10:9 Neither let us tempt Christ, as some of them also tempted, and were destroyed of serpents [see A Journey Without A Destination]. ^10:10 Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer.

^10:11 Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come. ^10:12 Wherefore let him that thinketh he standeth take heed lest he fall."

No mere human can pay the atonement price for all of humanity. Aaron's priesthood was merely a portrayal of the Son of God who would come to do what no man could.

"^9:11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building [see The Messiah's Triumphal Entry Into The Temple]; ^9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us [see the Fact Finder question below and What Is Jesus Christ Doing Right Now?].

^9:13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: ^9:14 How much more shall the blood of Christ [see Why Blood?], who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

^9:15 And for this cause he is the mediator of the new testament [see Covenant and Testament], that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance." (Hebrews 9:11-15 KJV)
