“Yahweh said to Moses. ‘Take sweet spices, stacte, and onycha, and galbanum, sweet spices with pure frankincense. Each part shall be equal. Make incense blended as by the perfumer, seasoned with salt, pure and holy. You shall beat some of it into powder, and put part of it before the covenant in the tent of meeting where I shall meet with you. It shall be for you most holy. When you make incense according to this composition, you shall not make it for yourselves. It shall be regarded by you as holy to Yahweh. Whoever makes any like it to use as perfume shall be cut off from the people.’”
Yahweh even told them how to make incense. This is a simple recipe with equal amounts of sweet spices, stacte, onycha, galbanum, and frankincense seasoned with salt, beat into a powder. This mixture of ancient spices also has a warning. You cannot use it for yourselves as a perfume, because it is holy for Yahweh. If you profane it, you will be cut off from the people.
