Exodus 30:36-38

36And you shall beat some of it very fine, and put some of it before the Testimony in the tabernacle of meeting where I will meet with you. It shall be most holy to you.

37But as for the incense which you shall make, you shall not make any for yourselves, according to its composition. It shall be to you holy for the Lord.

38Whoever makes any like it, to smell it, he shall be cut off from his people.”
