Exodus 30:35-37

35Give them to a worker who can use special skills to make the incense. It must have a sweet smell, like a perfume. Add some salt to it so that it is a pure and holy incense.

36Beat some of the incense to make powder. Put this in front of the Covenant Box, in the Tent of Meeting. That is where I will meet with you. This incense will be a very holy thing for you.

37Do not make any incense like this for yourselves. You must always think about it as very holy. It belongs to the Lord.
