Exodus 37:29. The incense, like the anointing oil, consisted of four aromatic ingredients.

Stacte - supposed to be either the gum of the Storax tree (Styrax officinale) found in Syria and the neighboring countries, or the gum known as Benzoin, or Gum Benjamin, which is an important ingredient in the incense now used in churches and mosques, and is the produce of another storax tree (Styrax benzoin) that grows in Java and Sumatra.

Onycha - , a perfume perhaps made from the cap of the strombus, or wing-shell, which abounds in the Red Sea.

Galbanum - , a gum of a yellowish brown color, in the form of either grains or masses. It is imported from India, Persia, and Africa; but the plant from which it comes is not yet certainly known.

Pure frankincense - This was the most important of the aromatic gums. Like myrrh, it was regarded by itself as a precious perfume Sol 3:6; Matthew 2:11, and it was used unmixed with other substances in some of the rites of the law. The tree from which it is obtained is not found in Arabia, and it was most likely imported from India by the Sabaeans, like Cinnamon, Cassia, and Calamus (see Exodus 30:23). The tree is now known as the Boswellia serrata, or B. thurifera, and grows abundantly in the highlands of India. The frankincense of commerce is a different substance, the resin of the spruce and of some other kinds of fir.

How a Private Man must Begin the Morning with Piety.
As soon as ever thou awakest in the morning, keep the door of thy heart fast shut, that no earthly thought may enter, before that God come in first; and let him, before all others, have the first place there. So all evil thoughts either will not dare to come in, or shall the easier be kept out; and the heart will more savour of piety and godliness all the day after; but if thy heart be not, at thy first waking, filled with some meditations of God and his word, and dressed, like the lamp in the tabernacle …
