And thou shalt make a vail of blue, and purple, and scarlet, and fine twined linen of cunning work: with cherubim shall it be made:

Wesley's Notes

26:31 The veils are here ordered to be made, one for a partition between the holy place and the most holy, which not only forbad any to enter, but so much as to look into the holiest of all. Under that dispensation divine grace was veiled, but now we behold it with open face. The apostle tells us, this veil, intimated that the ceremonial law could not make the comers thereunto perfect. The way into the holiest was not made manifest while the first tabernacle was standing; life and immortality lay concealed till they were brought to light by the gospel, which was therefore signified by the rending of this veil at the death of Christ. We have now boldness to enter into the holiest in all acts of devotion by the blood of Jesus; yet such as obliges us to a holy reverence, and a humble sense of our distance. Another veil was for the outward door of the tabernacle. Through this the priests went in every day to minister in the holy - place, but not the people, Heb 9:6. This veil was all the defence the tabernacle had against thieves and robbers, which might easily be broken through, for it could be neither locked nor bared, and the abundance of wealth in it, one would think, might be a temptation. But by leaving it thus exposed, The priests and Levites would be so much the more obliged to keep a strict watch upon it: and, God would shew his care of his church on earth, though it be weak and defenceless, and continually exposed. A curtain shall be (if God please to make it so) as strong a defence, as gates of brass and bars of iron.

Scofield Reference Notes

[1] vail

The inner veil, type of Christ's human body Mt 26:26 27:50 Heb 10:20. This veil, barring entrance into the holiest, was the most expressive symbol of the truth that "by the deeds of the law shall no flesh be justified" Rom 3:20, Heb 9:8. Rent by an unseen hand when Christ Died Mt 27:51 thus giving instant access to God to all who come by faith in Him, it was the end of all legality; the way to God was open. It is deeply significant that the priests must have patched together again the veil that God had rent, for the temple services went on yet for nearly forty years. That patched veil is Galatianism--the attempt to put saint or sinner back under the law. (Cf) Gal 1:6-9 Anything but "the grace of Christ" is "another gospel," and under anathema.

Matthew Henry's Concise Commentary

26:31-37 A vail, or curtain, separated the holy place from the most holy place. It was hung upon pillars. This vail was for a partition between the holy place and the most holy; which forbade any to look into the holiest of all. The apostle tells what was the meaning of this vail, Heb 9:8. That the ceremonial law could not make the comers thereunto perfect, nor would the observance of it bring men to heaven; the way into the holiest of all was not made manifest, while the first tabernacle was standing. Life and immortality lay hidden till they were brought to light by the gospel; which was signified by the rending of this vail at the death of Christ, Mt 27:51. We have now boldness to enter into the holiest, in all acts of worship, by the blood of Jesus; yet such as obliges us to holy reverence. Another vail was for the outer door of the tabernacle. This vail was all the defence the tabernacle had. God takes care of his church on earth. A curtain shall be, if God please to make it so, as strong a defence to his house, as gates of brass and bars of iron. With this typical description of Christ and his church before us, what is our judgment of these matters? Do we see any glory in the person of Christ? any excellence in his character? any thing precious in his salvation? or any wisdom in the doctrine of the cross? Will our religion bear examination? and are we more careful to approve our hearts to God than our characters toward men?
