Exodus 26:31, 33

“You shall make a veil of blue and purple and scarlet material and fine twisted linen; it shall be made with cherubim, the work of a skillful workman.

You shall hang up the veil under the clasps, and shall bring in the ark of the testimony there within the veil; and the veil shall serve for you as a partition between the holy place and the holy of holies.
