Exodus 30:36-38

Amplified Bible

³⁶ You shall crush some of it [into a] very fine [powder], and put some of it before the Testimony in the Tent of Meeting, where I will meet with you; it shall be most holy to you. ³⁷ The incense which you shall make, you shall not make in the same proportions for yourselves; it shall be holy to you for the Lord. ³⁸ Whoever makes any like it, to use as perfume shall be cut off from his people [excluding him from the atonement made for them].”
