Exodus 26:31-33

³¹"You shall make a veil of blue, and purple, and scarlet, and fine twined linen, with cherubim. The work of the skillful workman shall it be made. ³²You shall hang it on four pillars of acacia overlaid with gold; their hooks shall be of gold, on four sockets of silver. ³³You shall hang up the veil under the clasps, and shall bring the ark of the testimony in there within the veil: and the veil shall separate the holy place from the most holy for you.
