Exodus 30:34-36

34And Yhwh said unto Moses, Take unto thee sweet spices, stacte, and onycha, and galbanum; these sweet spices with pure frankincense: of each shall there be a like weight: 35And thou shalt make it a perfume, a confection after the art of the apothecary, tempered together, pure and holy:1 36And thou shalt beat some of it very small, and put of it before the testimony in the tabernacle of the congregation, where I will meet with thee: it shall be unto you most holy.
