Exodus 30:37

Revised Standard Version (RSV-CI)

And the incense which 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

And what is left of the cereal offering shall be for Aaron and his sons; it is a most holy part of the offerings by fire to the Lord.

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.”
