Exodus 26:31-34

“Make a curtain of fine linen and blue, purple, and red thread, and have a skilled craftsman sew designs of creatures with wings on it. Hang the curtain by gold hooks on four posts of acacia wood that are covered with gold, and set them in four silver bases. Hang the curtain from the hooks in the roof, and put the Ark of the Agreement containing the two stone tablets behind it. This curtain will separate the Holy Place from the Most Holy Place. Put the lid on the Ark of the Agreement in the Most Holy Place.
