Thematic Bible: Receipt for mixing

Jehovah said to Moses: Take one part fragrant spices and two kinds of gum resin and aromatic mollusk shells, and mix them with one part pure frankincense. Have a perfumer make it into fragrant incense, seasoned with salt, pure and holy. Grind some of it into a fine powder. Put it in front of the ark containing the words of my covenant in the tent of meeting, where I will meet with you. You must treat it as most holy.
