Exodus 30:35-37

New Century Version

³⁵ Make incense as a person who makes perfume would do. Add salt to it to keep it pure and holy. ³⁶ Beat some of the incense into a fine powder, and put it in front of the Ark of the Agreement in the Meeting Tent, where I will meet with you. You must use this incense powder only for its very special purpose. ³⁷ Do not make incense for yourselves the same way you make this incense. Treat it as holy to the Lord.
