Exodus 26:31-33
26:31 “You are to make a special curtain of blue, purple, and scarlet yarn and fine twisted linen; it is to be made with cherubim, the work of an artistic designer.
26:32 You are to hang it with gold hooks on four posts of acacia wood overlaid with gold, set in four silver bases.
26:33 You are to hang this curtain under the clasps and bring the ark of the testimony in there behind the curtain. The curtain will make a division for you between the Holy Place and the Most Holy Place.
