Was Eve Made From a Rib — Or From Adam's Side?

Most people who grew up in church know the scene by heart: God puts Adam into a deep sleep, removes one of his ribs, and builds Eve from it. But open the Hebrew text and the picture gets more complicated. The word behind “rib,” tsela (צֵלָע), shows up roughly forty times in the Old Testament. Outside Genesis 2, it is essentially never used for a bone in a human body. It is, overwhelmingly, an architectural term.

An Architect’s Word, Not an Anatomist’s

Flip to Exodus 25–27, where the tabernacle’s construction is specified in detail, and tsela repeatedly denotes the “side” of the ark or the tabernacle structure (Exodus 25:12, 14; 26:20, 26–27). In 1 Kings 6–7, describing Solomon’s temple, tsela refers to the side-chambers built against the temple wall (1 Kings 6:5–6) and to the planks or boards forming its floor and framing (1 Kings 6:15–16). Standard Hebrew lexicons — BDB and HALOT among them — list “side, flank” as the word’s basic sense, and treat the anatomical “rib” reading as resting on a single occurrence: Genesis 2:21–22.

That observation isn’t new or controversial on its own. The real debate starts one step further in: if tsela means “side,” what exactly does that imply about how Eve was made? Ziony Zevit, a Hebrew Bible scholar at American Jewish University, argued in his 2013 book What Really Happened in the Garden of Eden? (Yale University Press) that tsela in Genesis 2 doesn’t denote a single bone extracted from Adam, but a structural half of his body — that God divided the primordial human (adam) into two, rather than plucking out one piece. Read this way, the line makes better sense of Adam’s exclamation in Genesis 2:23, “This at last is bone of my bones and flesh of my flesh” — a description that fits a whole side of a body (bone and flesh together) more naturally than it fits a single extracted rib.

Zevit pushed the argument one step further with biologist Scott Gilbert in a short 2001 paper in the American Journal of Medical Genetics, “Congenital Human Baculum Deficiency: The Generative Bone of Genesis 2:21–23.” There they proposed that tsela specifically refers to the baculum — the penis bone present in most male mammals but conspicuously absent in humans — and suggested the text is offering an etiology for that anatomical gap. This more specific claim is a minority position even among scholars sympathetic to “side” over “rib.” Hebrew Bible scholar Claude Mariottini, surveying roughly eight different scholarly readings of tsela in Genesis 2, presents the baculum hypothesis neutrally as one option among several rather than a consensus view. Plenty of scholars accept “a side of the body” as the more defensible reading of tsela; far fewer sign on to the specific baculum claim.

Where “Rib” Actually Came From

So how did “rib” become so entrenched? The Septuagint translators rendered tsela with the Greek pleura, a word that itself could mean either “side” or “rib” — genuinely ambiguous. The narrowing happened later, when Jerome translated the Vulgate around 400 CE and chose costa, a Latin word that specifically means “rib.” Much of the Western translation tradition followed Jerome’s lead from there, and it shows: the KJV, and most major modern English versions (NIV, ESV, NASB among them) still render tsela as “rib” in Genesis 2. That’s worth noting for balance — this isn’t a case where scholarship has definitively overturned the traditional translation. It’s an open, ongoing debate, and serious scholars and major translations still favor “rib.”

Alongside that translation tradition, a persistent piece of folklore has traveled with it: the idea that men have one fewer rib than women because Adam’s was removed. It’s simply false. Since the sixteenth-century Flemish anatomist Andreas Vesalius performed actual human dissections and counted twelve pairs of ribs — twenty-four total — in both men and women, every generation of anatomists since has confirmed the same count. Even setting the anatomy aside, the logic doesn’t hold: removing a bone from one ancestor wouldn’t alter the genetic blueprint passed down to his descendants.

An Unsettled Question

Put together, the philology is on fairly solid ground: outside Genesis 2, tsela is a term for the side of a structure, not a bone. That much is well established, and it makes the traditional “rib” reading of Genesis 2 look narrower than it once seemed. What’s less settled is how far to take the reinterpretation — whether it means “a whole side of Adam’s body” in a general sense, or something as specific as the baculum hypothesis, or whether the traditional “rib” reading (with real linguistic roots of its own in the Septuagint and Vulgate) should simply be retained. This is a live conversation among Hebrew Bible scholars, not a closed case — and preachers and teachers handling this text should present it that way.
