In the Hebrew Bible incense is not a decorative element of worship but one of its most sacred and most regulated parts. It is called ketoret, a term linked to a root meaning rising smoke. Its recipe, its altar and the people authorised to offer it are described precisely, and stories have grown around it that underline both its power and its danger.
The recipe in Exodus
In chapter 30 of the Book of Exodus, God gives Moses instructions for preparing the incense of the Tabernacle. Four ingredients are named, in equal parts:
- Nataf, a dripping resin traditionally translated as "stacte" or storax;
- Sheḥelet, an aromatic substance rendered as "onycha", of uncertain identification;
- Ḥelbenah, galbanum, a resin with a sharp smell;
- Levonah zakah, pure incense, that is frankincense.
The blend was to be salted, pure and holy. The text adds a strict prohibition: no one could make a perfume of the same composition for personal use. The sacred incense belonged to God alone.
The presence of galbanum is interesting, since its smell on its own is not considered pleasant. Later Jewish commentators read a teaching in this detail: in the prayer of the community there must be room for everyone, even those who seem far away, because only the whole forms the complete offering.
The golden altar
The same chapter describes a specific altar for incense, overlaid with gold and placed before the veil that separated the holy place from the holy of holies. Aaron, and the priests after him, were to burn incense on it every morning and every evening, when they tended the lamps of the lampstand.
This daily rhythm tied incense to light and to time: the fragrant offering accompanied the beginning and the end of the day, like a continuous prayer.
The Day of Atonement
The most solemn moment in which incense appears is described in chapter 16 of Leviticus, devoted to Yom Kippur. Once a year the high priest entered the holy of holies carrying a censer of coals taken from the altar and two handfuls of finely ground incense. Before the mercy seat, the cover of the ark, he threw the incense onto the coals so that the fragrant cloud would cover the place of the divine presence.
Here the cloud of incense had a precise meaning: it created a veil between man and the glory of God, making approach possible without being overwhelmed.
The stories of strange fire
The Bible stresses that incense is not offered at will. In chapter 10 of Leviticus we read that Nadab and Abihu, sons of Aaron, offered before the Lord a "strange fire" that had not been commanded, and were consumed by fire that came out from the divine presence. In the Book of Numbers, Korah's rebellion ends with a test of censers, showing who is truly chosen for service.
These stories convey a strong idea: incense is sacred because it touches the point of contact between the human and the divine, and for that very reason it demands order, respect and legitimacy.
The rabbinic tradition: eleven spices
Rabbinic literature expands the biblical recipe. A passage of the Talmud, still recited in many communities during prayer under the name Pitum ha-ketoret, lists eleven spices, among them myrrh, cassia, spikenard, saffron and cinnamon, together with other ingredients such as salt and a herb called ma'aleh ashan, "that makes the smoke rise".
The Talmud also recalls the priestly family of Avtinas, charged with preparing the incense, who guarded the secret of this herb and of how to make the smoke rise straight like a column.
From altar to prayer
After the destruction of the Temple in 70 AD, sacrifices and incense ceased. Yet the Jewish tradition preserved the memory of the ketoret in the liturgy, turning the recitation of texts into a form of offering. Psalm 141 expresses this with an image destined for great fortune: "Let my prayer be set before you as incense."
| Element | Symbolic meaning |
|---|---|
| Four ingredients in equal parts | Balance and completeness |
| Galbanum | Including what seems imperfect |
| Golden altar before the veil | Closeness to the mystery |
| The Yom Kippur cloud | A veil that protects and reveals |
