Equality is also very beautifully displayed in respect of the composition of spices for purposes of fumigation; for we read, "Take to thyself sweet odours, stacte, onycha, galbanum, these sweet spices with pure frankincense, all of the most chosen kinds, all of equal weight and thou shalt make of it a perfume, a confection, after the art of the apothecary, a pure composition, a holy work." Exodus xxx. 34 For the Lord enjoins here that each of the separate portions shall be equal to each, with a view to the proper composition of the whole.

And as I imagine these four ingredients of which the entire perfume is composed are emblems of the four elements of which the whole world is made; he likens the stacte to water, the onycha to land, the galbanum to the air, and the pure transparent frankincense to fire; for stacte, which derives its name from the drops (σταγόνες) in which it falls is liquid, and onycha is dry and earth-like, the sweet smelling galbanum is added by way of giving a representation of the air, for there is fragrance in the air; and the transparency which there is in frankincense serves for a representation of fire.

On which account also, he has separated the things which have weight from those which are light, uniting the one class by a closely connecting combination, and bringing forth the other in a disunited form; as where he says, "Take to thyself sweet odours, stacte, onycha," these things being weighty he mentions unconnectedly, being the symbols of earth and water. Afterwards he begins afresh with the other class, which he mentions in combination, saying, "And the sweet spice of galbanum and the transparent frankincense," these again being in their own nature emblems of the light things, air and fire.

And the harmonious composition and mixture of these things is truly his most ancient and most perfect holy work, Numbers vii. 5. Exodus xxx. 34 namely, the world; which, speaking of it under the emblem of perfume, he thinks is bound to show gratitude to its Creator. So that in name the composition which has been carefully fabricated by the art of the apothecary may be offered up, but in real fact the whole world which was created by divine wisdom may be consecrated and dedicated, being made a burnt offering of early in the morning and also in the evening.

For such a life as this becomes the world, namely, continually and without ceasing to be giving thanks to its Father and Creator, so as to stop short of nothing but evaporating and reducing itself into its original element, in order to show that it stores up and conceals nothing, but dedicates itself wholly as a pious offering to God who created it.
