Exodus 30:37

The English Standar Version

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.

See the chapter Copy

Seven days you shall make atonement for the altar and consecrate it, and the altar shall be most holy. Whatever touches the altar shall become holy.

Whoever makes any like it to use as perfume shall be cut off from his people."

But the rest of the grain offering shall be for Aaron and his sons; it is a most holy part of the LORD's food offerings.
