Exodus 26:31; Exodus 26:33

31 "And you shall make a veil of blue and purple and scarlet yarns and fine twined linen. It shall be made with cherubim skillfully worked into it.

33 And you shall hang the veil from the clasps, and bring the ark of the testimony in there within the veil. And the veil shall separate for you the Holy Place from the Most Holy.
