Read Exodus 30:37 Using Other Translations
And as for the perfume which thou shalt make, ye shall not make to yourselves according to the composition thereof: it shall be unto thee holy for the LORD.
And the incense that you shall make according to its composition, you shall not make for yourselves. It shall be for you holy to the LORD.
Never use this formula to make this incense for yourselves. It is reserved for the LORD, and you must treat it as holy.
