Exodus 26:31-34

31“Make a curtain of blue, purple and scarlet yarn and finely twisted linen, with cherubim woven into it by a skilled worker. 32Hang it with gold hooks on four posts of acacia wood overlaid with gold and standing on four silver bases. 33Hang the curtain from the clasps and place the ark of the covenant law behind the curtain. The curtain will separate the Holy Place from the Most Holy Place. 34Put the atonement cover on the ark of the covenant law in the Most Holy Place.
