What is the tree of life, and what happened to it?

The tree of life makes its first appearance in Genesis 2:9, in the original description of the garden:

"And out of the ground the LORD God made to spring up every tree that is pleasant to the sight and good for food. The tree of life was in the midst of the garden, and the tree of the knowledge of good and evil." (Gen 2:9)

It is a real tree, at the center of a real garden. The text makes no apology for describing it and no effort to explain what it is metaphorically. It is "the tree of life" — the tree whose fruit sustains life.

Why it mattered

After the fall, God says something that explains why this tree was so significant:

"Then the LORD God said, 'Behold, the man has become like one of us in knowing good and evil. Now, lest he reach out his hand and take also of the tree of life and eat, and live forever—' therefore the LORD God sent him out from the garden of Eden." (Gen 3:22–23)

The tree's fruit had the capacity to make a person live forever. That is not a small thing. God's concern is not that the tree is bad — it is that access to eternal life for a now-corrupted humanity would lock sin in permanently. The expulsion is not purely punitive; it is also, in a strange way, merciful. Eternal life in a broken state would be an eternal curse.

The cherubim and the flaming sword

God places two guards at the east of Eden:

"He drove out the man, and at the east of the garden of Eden he placed the cherubim and a flaming sword that turned every way to guard the way to the tree of life." (Gen 3:24)

The keruvim (כְּרוּבִים, H3742) are not the chubby baby-angels of Renaissance painting. Elsewhere in the OT, cherubim are the living creatures who carry the divine throne (Ezk 1:5–14; 10:1–22), whose images are embroidered on the curtain of the tabernacle (Exo 26:31), and whose carved forms guard the ark of the covenant (Exo 25:18–20). They are guardians of divine holiness. Placing them at Eden's gate makes the point: access to the tree of life has become a matter of holiness, not just geography.

The lahat hacherev hammithapheketh (לַהַט הַחֶרֶב הַמִּתְהַפֶּכֶת) — "the flaming, turning sword" — is unique in the OT. Whatever it is, it is the active, mobile barrier between fallen humanity and life.

The tree of life in Proverbs and Ezekiel

Between Genesis and Revelation, the tree of life surfaces as a figure of speech in Proverbs:

• "She [Wisdom] is a tree of life to those who lay hold of her" (Pro 3:18)
• "The fruit of the righteous is a tree of life" (Pro 11:30)
• "A gentle tongue is a tree of life" (Pro 15:4)

Proverbs does not bring back the actual tree; it borrows its image to describe life-giving realities in the present. Ezekiel's great vision of the renewed temple features fruit trees on both sides of the river flowing from the sanctuary, with leaves for healing (Ezk 47:12) — a vision that leans into the Eden imagery without naming the tree of life explicitly.

Revelation: the tree restored

The last pages of the Bible close the loop opened in Genesis 3:

"Then the angel showed me the river of the water of life, bright as crystal, flowing from the throne of God and of the Lamb through the middle of the street of the city; also, on either side of the river, the tree of life with its twelve kinds of fruit, yielding its fruit each month. The leaves of the tree were for the healing of the nations." (Rev 22:1–2)

And then:

"Blessed are those who wash their robes, so that they may have the right to the tree of life and that they may enter the city by the gates." (Rev 22:14)

What the cherubim and the flaming sword block in Genesis 3:24, the blood of the Lamb unlocks in Revelation 22:14. The tree does not disappear from the story; it waits at the end of it. The whole arc of Scripture is, among other things, the story of how humanity lost access to the tree of life and how God, at enormous cost, restored it.

Eden's east gate guarded by cherubim becomes the city's open gates (Rev 21:25: "its gates will never be shut by day"). The flaming sword that "turned every way" is replaced by the tree that produces fruit every month. What was blocked is now abundant.
