Keep reading in Exodus. I've already explained this in this thread. Nonetheless, at Exodus 20:19 And they said unto Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die.
So, what did God do?
28:1 And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, [even] Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
He separated the Levitical line out from the 12 and called the other 11 the children of Israel. This distinction carries forward to Acts 5:21.
Okay? Now, what is the NT model? Melchizedek, assuming one does not shrink back, but the just shall live by faith (hearing/seeing the Word, Scripture guided by the Holy Spirit). We are the priesthood of believers. What model? Not the 1 and 11 of the OT Levitical priesthood (incidentally this is the RCC and others model), but this wherein all may be elders:
born-again from above, baby, weaned (from milk to meat), elder.
The part where you make the assumption that Exodus 20:19 is the cause of the setting up the Priesthood in Exodus 28:1-.
Eisegesis
and the part about all being elders.
Eisegesis
Forgive me...
So, you agree there was a singluar Levitical priesthood and 11 other tribes known as the children of Israel? But disagree as to why God did this?
Ex. 19:6 And ye shall be unto me a kingdom of priests, and an holy nation. These [are] the words which thou shalt speak unto the children of Israel.
Ex. 20:19 And they (the people) said unto
Moses, Speak thou with us, and we will hear: but let not God speak with us, lest we die.
Ex. 28:1 And take thou (
Moses) unto thee
Aaron thy brother, and his sons with him,
from among the children of Israel, that he may minister unto me
in the priest's office, [even] Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
Deut. 17:18 And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of [that which is] before
the priests the Levites:
2 Chron. 29:21 And they brought seven bullocks, and seven rams, and seven lambs, and seven he goats, for a sin offering
for the kingdom, and for the sanctuary, and for Judah. And he
commanded the priests the sons of Aaron to offer [them] on the altar of the LORD.
Clearly there is a distinction between the priests and the people. This was not the original intent in the OT, nor in the NT.
There is a different model shown in the NT for those of the lineage of the priesthood of Melchizedek with Jesus Christ as our High Priest. Surely you agree that Jesus was of the tribe of Judah? Change in the Law? Change of the priesthood?
