I am a bit in two minds about posting this. We all have our irony of not being perfect and a Christian perspective changes the narrative of the importance placed on such structures. Israel being on the other side of the world pushes it towards out of sight out of mind. For Israel, there were lasting ordinances in terms of priestly duties which included the Holy Of Holies.
In many ways, that is the card they are playing. Rebuilding the temple and rededicating the Holy of Holies. This brings me to wonder why they never rededicated a Holy Of Holies for a rebuilt Tabernacle while they waited for the Temple to be rebuilt. It's what happened in the bible but it looks like they will roll out the necessary holy objects when they have built the Temple. What a coincidence if that happens. Mums the word on Israel re-doing a Tabernacle of David by the looks of it as well while they waited for like the last 70 years.
The Holy of Holies (Hebrew: קֹדֶשׁ הַקֳּדָשִׁים Qōḏeš haqQŏḏāšīm or Kodesh HaKodashim; also הַדְּבִיר haDəḇīr, 'the Sanctuary') is a term in the Hebrew Bible that refers to the inner sanctuary of the Tabernacle, where God's presence appeared. According to Hebrew tradition, the area was defined by four pillars that held up the veil of the covering, under which the Ark of the Covenant was held above the floor. According to the Hebrew scripture, the Ark contained the Ten Commandments, which were given by God to Moses on Mount Sinai. The Temple in Jerusalem was said to have been built by King Solomon for keeping the Ark.
According to the Bible, the Holy of Holies was covered by a veil,[8] and no one was allowed to enter except the High Priest, and even he would only enter once a year on Yom Kippur,[9] to offer the blood of sacrifice and incense. The Bible reports that in the wilderness, on the day that the tabernacle was first raised up, the cloud of the Lord covered the tabernacle (Exodus 40:33–40:34). There are other times that this was recorded, and instructions were given that the Lord would appear in the cloud upon the mercy seat (kapporet), and at that time the priests should not enter into the tabernacle (Leviticus 16:2). According to the Hebrew Bible, the Holy of Holies contained the Ark of the Covenant with representation of Cherubim.
Upon completion of the dedication of the Tabernacle, the Voice of God spoke to Moses "from between the Cherubim" (Numbers 7:89).
Day of Atonement
The Holy of Holies was entered once a year by the High Priest on the Day of Atonement, to sprinkle the blood of sacrificial animals (a bull offered as atonement for the Priest and his household, and a goat offered as atonement for the people) and offer incense upon the Ark of the Covenant and the mercy seat that sat on top of the ark in the First Temple (the Second Temple had no ark and the blood was sprinkled where the Ark would have been and the incense was put on the Brazen Altar of incense). The animal was sacrificed and the blood was carried into the most holy place. The gold was also found in the Most Holy Place.
