Exodus 26:31-33

“You shall make a veil [to divide the two rooms] of blue, purple, and scarlet fabric and fine twisted linen, skillfully worked with cherubim on it. You shall hang it on four pillars (support poles) of acacia wood overlaid with gold, with gold hooks, on four silver sockets. You shall hang the veil from the hooks [that connect the curtains together], and you shall bring the ark of the Testimony there within the veil. The veil shall separate for you the Holy Place and the Holy of Holies.
