Exodus 26:31–33
Make a veil of blue, purple, and scarlet yarn, and finely spun linen, with cherubim skillfully worked into it. / Hang it with gold hooks on four posts of acacia wood, overlaid with gold and standing on four silver bases. / And hang the veil from the clasps and place the ark of the Testimony behind the veil. So the veil will separate the Holy Place from the Most Holy Place.
