Exodus 30:36-38

36And thou shalt beat [some] of it to powder, and put [some] of it before the testimony in the tent of meeting, where I will meet with thee: it shall be unto you most holy. 37And the incense that thou shalt make, ye shall not make for yourselves according to the proportions of it; it shall be unto thee holy to Jehovah. 38Whoever maketh like unto it, to smell it, shall be cut off from his peoples.
