Exodus 26:31-33

31And thou shalt make a veil of blue, and purple, and scarlet, and twined byssus; of artistic work shall it be made, with cherubim.

32And thou shalt attach it to four pillars of acacia-wood overlaid with gold, their hooks of gold; they shall be on four bases of silver.

33And thou shalt bring the veil under the clasps, and bring in thither, inside the veil, the ark of the testimony; and the curtain shall make a division to you between the holy [place] and the holiest of all.
