veil of blue: Parachoth:, from parach:, to separate, divide, make a distinction between somewhat, the inner vail, which divided the tabernacle into two, and separated, and made a distinction between the Holy place and the Holy of Holies.
This vail was made of the same rich materials as the inner covering of the tabernacle, and curiously embroidered with cherubim and other ornaments. Though it does not appear from Scripture at what distance from either end of the tabernacle this vail was hung, yet is reasonably conjectured, that it divided it in the same proportion in which the temple, built after this model, was divided; that is, two-thirds of the whole length were allotted to the first room, and one-third to the second; so that the room beyond the vail, the Holy of Holies, was exactly square, being ten cubits each way, and the first room, the sanctuary, was twice as long as it was broad.
