The Olive Tree in the Bible and Quran

Few plants have shaped human spirituality as profoundly as the olive tree. Across the two largest Abrahamic faiths — Christianity and Islam — the olive appears not as decoration but as a vessel of meaning: anointing, kingship, prayer, prophecy, and divine blessing. Its presence in both the Bible and the Quran is neither coincidental nor superficial. It reflects a shared reverence for a tree that sustained the ancient Mediterranean world in body and soul.

The Anointed One

In the Hebrew Bible, olive oil is the substance that makes kings. The Book of 1 Samuel (16:13) describes the prophet Samuel taking a horn of oil and anointing the young David in the midst of his brothers: "and the Spirit of the Lord came powerfully upon David from that day on."

This act — pouring olive oil over someone's head — was not symbolic in the way we might understand symbolism today. It was transformative. The anointing conferred divine authority. It was the moment a shepherd boy became the future king of Israel.

The word "Messiah" comes from the Hebrew mashiach, meaning "the anointed one." In Greek, this becomes Christos — Christ. The entire theological foundation of Christianity rests, etymologically and ritually, on the act of anointing with olive oil. When Christians speak of Jesus as the Christ, they are, at root, speaking of someone anointed with oil from the fruit of a tree.

The Mount of Olives and the Garden of the Press

The geography of the Gospels is saturated with olive imagery. The Mount of Olives — Har HaZeitim in Hebrew — rises east of Jerusalem's Old City. Its name translates literally as the "Mount of Anointing." This is where Jesus wept over Jerusalem, where he taught his disciples about the end of days, and where, according to Christian tradition, he ascended to heaven.

At the foot of this mount lies the Garden of Gethsemane, and its name is perhaps even more revealing. Gethsemane comes from the Aramaic gat shemanim, meaning "olive press." This was, quite literally, a place where olives were crushed to extract their oil.

The symbolism is difficult to ignore. In Christian theology, Gethsemane is where Jesus spent his final night before arrest, praying in anguish so intense that, according to the Gospel of Luke, his sweat fell like drops of blood. He was, in the language of the place itself, being pressed — crushed under the weight of what was to come — in a garden named for the pressing of olives. The parallel between the crushing of fruit to yield precious oil and the suffering of a man to yield salvation has been noted by theologians for centuries.

Ancient olive trees still grow in the Garden of Gethsemane today. Some have been dated to nearly a thousand years old, and while they are not the same trees that stood in Jesus's time, they are likely descended from them — grown from the roots of their ancestors, as olive trees do.

Oil in Christian Practice

Beyond scripture, olive oil became embedded in Christian ritual. The sacrament of anointing the sick (sometimes called Last Rites or Extreme Unction) uses blessed olive oil. Baptismal rites in many traditions involve anointing with chrism — a consecrated oil typically made from olive oil and balsam. The oil of catechumens, used in preparation for baptism, is olive oil blessed by a bishop.

In the Eastern Orthodox tradition, oil lamps burning olive oil are kept lit before icons in churches and homes. The oil is not incidental — it is the same substance that anointed kings, that burned in the Temple, that was pressed from the fruit of a tree given by God.

The Blessed Tree of Islam

The olive holds a place of equally profound reverence in Islam. The Prophet Muhammad is recorded as saying: "Eat olive oil and anoint yourselves with it, for it comes from a blessed tree" (at-Tirmidhi 1851, Ibn Majah 3319). This hadith — a saying of the Prophet preserved in the collections of his companions — is among the most frequently cited in discussions of food and health in Islamic tradition.

The instruction is notable for its directness. Muhammad does not merely suggest olive oil or recommend it. He frames it as coming from a blessed tree — a tree that carries divine favour. For the roughly two billion Muslims in the world today, this hadith remains a living guide to diet and self-care.

The Quran itself goes further. In Sura At-Tin (95:1), Allah opens with an oath: "By the fig and the olive." In Arabic rhetoric, a divine oath elevates its subject to the highest possible status. When God swears by something, that thing is sacred. The olive, alongside the fig, is granted this distinction in the very first verse of the chapter.

Across the Quran, the olive tree is mentioned in eight separate verses. In Sura An-Nur (24:35), the famous "Verse of Light," the olive tree appears in one of the most beautiful and mysterious passages in all of Islamic scripture:

"Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a pearly star lit from a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire."

The image is extraordinary: an olive tree so blessed that its oil nearly shines of its own accord, without flame. It is a metaphor for divine knowledge — light that comes from within, fuelled by something pure and self-sustaining.

A Shared Inheritance

What is striking about the olive's role in both traditions is not just its presence but its consistency. In both the Bible and the Quran, the olive tree represents blessing, sustenance, light, and the sacred. It is not a metaphor borrowed from one faith by another — it is a shared inheritance from the ancient Mediterranean world, where the olive tree was already the most important plant in human civilisation long before either scripture was written.

The reverence runs deeper than theology. It reflects a lived reality. For the people who first told these stories, olive oil was not a luxury or a condiment. It was light in the darkness — literally, in oil lamps — and nourishment for the body, and medicine for the sick, and the substance that marked the boundary between the ordinary and the holy.

When you open a bottle of Cretan extra virgin olive oil today, you are holding something that two of the world's great faiths consider blessed. The trees that grow across Crete's hills and valleys are the same species, producing the same fruit, yielding the same golden-green oil that has carried sacred meaning for three thousand years. That is not a marketing claim. It is simply what the olive tree is.
