Greetings to you Aaron and grace and hope to you and yours. Thank you for your insights and wisdom on this matter.
The gems on the breastplate of the high priest signify who was represented on the day of atonement, and it was the Twelve Tribes...the house of Israel...the circumcision...the elect
In regard to your statement above. I think that you are accurate except for the added part at the end. There is no explicit nor implicit verse that tells us that the High Priest sacrifice (the Jewish sacrifice) made once a year called the Day of Atonement or Yom Kippur is for "the elect".
Now, I'm not discounting at this point that it is not a "representation" or "shadow" of what Christ did for the elect. Just pointing out and being strict with biblical accuracy that The Day of Atonement (Lev 16:21-22, Heb 9:7), also known as Yom Kippur gives no mention of "the elect" and no mention of only being for 'some Jews'.
The biblical text explicitly says...
"confess over it all the iniquities of the children of Israel, and all their transgressions, concerning all their sins"... (upon the sacrificial goat). It was for the "peoples sins committed in ignorance" (Heb 9:7).
It would seem that if one was going to bring an argument that this sacrifice was only of the "elect" then one would focus on the phrase "children of Israel" in Lev 16. The only problem is that if one studies Jewish tradition one clearly understands that the Day of Atonement was for 'every Jew' not just some.
There was no stone for uncircumcised Egypt, which represents the world.
We agree that the sacrifice did not include Egypt or anyone outside of the Jewish people.
In the individual sacrifices, we see Christ dying for the individual. On the day of atonement, we see Christ dying for the nation.
We agree that the individual sacrifices were shadows of Christ dying for the individual (i.e., elect). Where we would seem to disagree, or I'm just not clear, is your statement that the Day of Atonement was Christ dying for "the nation".
Within the biblical text, the sacrifice that was given once a year was for 'people', their sins and transgressions of ignorance (not a nation but the people within the nation). And here is the rub, Paul tells us that not all the circumcised Jews were children of the promise (i.e., elect). Maybe even most were not Jews of the promise but only Jews of the seed.
In other words, the Priests are giving sacrifices for
all Jews, yes all symbolically are circumcised, but not all of them were children of the promise.
Thoughts?
Peace to you brother
