What did the veil prevent the priests from seeing in their daily service?
The veil prevented the priests from seeing the presence of God in the Holy of Holies during their daily service. They could come only up to the veil, while the high priest alone entered behind it once a year. The veil pictured the body of Christ and separated the Holy of Holies from the main sanctuary.
Les explains that the veil separated the Holy of Holies from the main sanctuary and kept the presence of God from the view of the priests as they practiced their daily ministrations. They would only come up to the veil. Only the high priest, once a year, would come in behind the veil, which relates to the Day of Atonement. The veil pictures the very body of Christ. It was made of blue, purple, and scarlet, and fine twine linen, with cherubim, and was hung on four pillars of acacia wood overlaid with gold. At the crucifixion, the veil was rent from the top to the bottom, not bottom to top, signifying no man had anything to do with it; it was an act of God. Behind the veil sat the Ark of the Covenant, which became the mercy seat, overshadowed by cherubim.
