who was allowed in the most holy place
Holy of Holies The Holy of Holies was covered by a veil, and no one was allowed to enter except the High Priest, and even he could only enter once a year on Yom Kippur (the day of atonement), to offer the blood of sacrifice and incense before the mercy seat. 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).
Holy Spirit in Christianity The term Holy Spirit appears at least 90 times in the New Testament.[7] The sacredness of the Holy Spirit to Christians is affirmed in all three Synoptic Gospels (Matthew 12:30–32, Mark 3:28–30 and Luke 12:8–10) which proclaim that blasphemy against the Holy Spirit is the unforgivable sin.[33] The participation of the Holy Spirit in the Trinity is suggested in Jesus' final post-Resurrection instruction to his disciples at the end of the Gospel of Matthew (28:19):[34] "Go ye therefore, and make disciples of all the nations, baptizing them into the name of the Father and of the Son and of the Holy Spirit".[14]
