Exodus 26:31-33

31“You are to make a curtain of blue, purple, and scarlet yarn, and finely spun linen with a design of cherubim worked into it.

32Hang it on four gold-plated pillars of acacia wood that have gold hooks and that stand on four silver bases.

33Hang the curtain under the clasps and bring the ark of the testimony there behind the curtain, so the curtain will make a separation for you between the holy place and the most holy place.
