Now, to the business at hand.
I will also note its author.
First of all, the ceremonial laws included more than the sacrifices,
they also included the food laws and the purification laws.
1) The ceremonial laws were spoken by God to Moses (Lev 1:1, 4:1, 5:14, 6:1, 8, 19, 24,
7:22, 28, 8:1, 11:1, 12:1, 13:1, 14:1, 33, 15:1, 16:1, 17:1, 18:1, 19:1, 20:1, 21:1, 16,
22:1, 17, 26, 23:1, 9, 23, 26, 33, 24:1, 13, 25:1, 27:1), who then spoke them to the people.
The ceremonial laws did not originate with Moses, their author and giver is God.
2) Scripture does not state that Moses wrote in a book the ceremonial laws in Leviticus,
which were given in the Tabernacle (Ex 25:22; Lev 1:1).
Scriptures states that Moses wrote down everything the Lord had said on the mountain
in Ex 20-24 (Ex 24:4).
3) The ceremonial laws of Leviticus which were given in the Tabernacle were not placed beside the Ark.
The renewal of the law by Moses in the wilderness of Moab was placed beside the Ark.
15) The ceremonial laws of Leviticus given in the Tabernacle (Ex 25:22, Lev 1:1) were not mediated
by angels.
You should know this.
