Exodus 30:35-37

Living Bible

³⁵ using the usual techniques of the incense maker, and seasoning it with salt; it shall be a pure and holy incense. ³⁶ Beat some of it very fine and put some of it in front of the Ark where I meet with you in the Tabernacle; this incense is most holy. ³⁷ Never make it for yourselves, for it is reserved for the Lord and you must treat it as holy.
