Exodus 26:31-33

31Make a veil of blue, purple, and scarlet yarn, and finely spun linen, with cherubim skillfully worked into it. 32Hang it with gold hooks on four posts of acacia wood, overlaid with gold and standing on four silver bases. 33And hang the veil from the clasps and place the ark of the Testimony1 behind the veil. So the veil will separate the Holy Place from the Most Holy Place.2
