Exodus 30:34-36

Incense 34Then the LORD said to Moses, “Take fragrant spices—gum resin, onycha and galbanum—and pure frankincense, all in equal amounts, 35and make a fragrant blend of incense, the work of a perfumer. It is to be salted and pure and sacred. 36Grind some of it to powder and place it in front of the ark of the covenant law in the tent of meeting, where I will meet with you. It shall be most holy to you.
