Tx for bringing this to our attention. It is very interesting indeed. I never really studied deeply Ezekiel's temple and services but I do agree with you that it points to the Priesthood and their ministry at Jesus 2nd coming. I will give you my impression from reading and reflecting on Ez 45 just now.
Ezekiel's temple has a double atonement in the spring spanning a week
I think that (v.18-20) could be an atonement type but moreso the cleansing atonement found in Lev 14 than the fall Day of atonement. My first impression from reading verse 1-17 that it could be also a peace offering. Peace offerings are also known as offerings of reconciliation(atonement) that some texts in Eze 45 mentions.
The day of atonement or the atonement for cleansing lepers or a house infected with the plague of Leprosy was with 2 animals ahowever it never lasted for 7 days, but the priest did come to inspect the person or the house after 7 days.
Do notice that Eze 45:18-20 does not say that it lasted a week long either. v.18 does mention about offering a bull on the 1st day of the 1st month; however notice what v.20 says AV Ezk 45:20
And so thou shalt do the seventh [day] of the month for every one that erreth, and for [him that is] simple: so shall ye reconcile the house.. No mention of sacrifice.
To me what the simple text says on the 1st day of the first month to apply the blood of the bull for the sanctuary by applying on the posts and altar. On the 7th day of the first month(v.20), it doesn't mention any specifics in terms of sacrifices, but does points to mediate for the sinners: "
for every one that erreth, and for him that is simple: so shall ye reconcile the house".
So it does resemble a type of cleansing rituals of the house mentioned in Lev 14:33-53 in terms of
1) historical timing: "
When ye be come into the land of Canaan, which I give to you for a possession, and I put the plague of leprosy in a house of the land of your possession;"(Lev 14:34). Our body is the temple(house) of the Lord. The same applies corporately all the believers of the Church form the temple. So Ez 45 seems to be pointing at the time of possessing the Kingdom and the need to do a cleansing ritual in a corporate level of the house(church).
2)the days : the 1st & the 7th similar to a cleansing rituals found in Lev 14:9 & 38.
3)and putting blood on the posts: I know the posts of a house at passover symbolizes the ears(that now is incline to the voice of the Lord). However the altar represents the heart; so the 4 corners of the altar could mean the corporate heart of all the believers of the earth??? The cleansing ritual applies blood on 4 extremity body parts: the 2 ears, the right thumb, and right toe.(Lev 14:14). Could that be linked to the 4 corner of the altar? I don't know. Applying blood on the two posts is similar to the Passover ritual.
4)but I still don't see the two animals normally in a cleansing(atonement) ritual; unless Eze 45 only describes the sin offering of the atonement service. That is not unusual to not have everything mentioned in one text or law but find different information spread in 2 or several related laws that you need to group together to see the whole law about the matter.
Notice that Eze 45:1-8 talks about possessing the land and dividing the lot. This leads me to think the timing of this order of Priesthood is after Jesus second coming when we will "enter the Promised Land" and the kingdom will be transfered to the Saints of the Most High(Dan 2 & 7).
Then Eze 45:9-12 talks about the Princes of Israel(Priests or Saints of the Most High) that will "
remove violence and spoil, and execute judgment and justice"(v.9). Up to there it makes sense to me that the Saints of the Most High would do a cleansing of the land by execute judgment and justice at that point of time as reveal in Rev 19:11-15 and elsewhere. However continuing in v.9, I don't know what "
take away your exactions(grushah) from my people"means in v. The word g
rushah has only one occurence and it's translation "exaction" seems not in harmony with the meaning of its root word which is
garash that means "to drive out of possession"
Then we have from v. 13-25 some sacrifices and the feasts listed. I view these to be all symbolic having a spiritual meaning of events, work and intercession that needs to take place by the Priesthood, in the Church, in the peoples hearts and in the land recently inherited by which v.1-8 talks about.
Something I have learned that all the 3 feasts(Passover, Pentecost, and Tabernacles) were marked by events and only set during when these events first occured. So since there is no set feast on the 1st day of the 1st month, I see v.18-20 a new feast added to commemorate a new event : the new era(the Millenium) of the Saints of the Most High being put in charge of the Kingdom(Dan 2 & 7). I think(and I maybe wrong) that the cleansing ritual of Lev 14 does aligns with this events.
Besides that the other two feasts mentioned is the regular passover with the regular 7 days of unleavened bread and the regular 7 days feast of Tabernacle. Nothing new or unusual there.
