Ark of The Covenant 3

Hebrews 9
Worship in the Earthly Tabernacle
1Now the first covenant had regulations for worship and also an earthly sanctuary. 2A tabernacle was set up. In its first room were the lampstand, the table and the consecrated bread; this was called the Holy Place. 3Behind the second curtain was a room called the Most Holy Place, 4which had the golden altar of incense and the gold-covered ark of the covenant. This ark contained the gold jar of manna, Aaron's staff that had budded, and the stone tablets of the covenant. 5Above the ark were the cherubim of the Glory, overshadowing the atonement cover. But we cannot discuss these things in detail now.

But we cannot discuss these things in detail now?

Just when we get interested the writer says “But we cannot discuss these things in detail now.”

Maybe they could not discuss those things in detail then but now we can

When the priests lifted The Ark they lifted what was inside the Ark. So they also lifted up the gold jar of manna, Aaron's staff that had budded, and the stone tablets of the covenant. What were they lifting up?

Gold jar of manna = Bread of Heaven = Jesus Christ.

Aaron's staff that had budded = Authority of The High priest = Authority of Jesus Christ.

The stone tablets of the covenant = Word of The Father = Jesus Christ.

But they are not just shadows of Christ.

The Stone Tablets were of The Father, The Manna was of the Son, Christ The Bread of Heaven and Aarons staff was the staff that comforts, the comforter is The Holy Spirit.

6When everything had been arranged like this, the priests entered regularly into the outer room to carry on their ministry. 7But only the high priest entered the inner room, and that only once a year, and never without blood, which he offered for himself and for the sins the people had committed in ignorance

The old Covenant Church served Christ.
