Did God take a 'rib' or a 'side' from Adam in Genesis 2?

The traditional translation says God took a "rib" from Adam, but that word almost certainly isn't right. The Hebrew is tsela (צֵלָע, H6763), and in 38 of its 40 appearances in the Old Testament, it means the side of a structure — the side of the tabernacle (Exodus 26:20), the sides of the ark of the covenant (Exodus 25:12), the side-chambers of Solomon's temple (1 Kings 6:5), the flanking rooms of Ezekiel's temple vision (Ezekiel 41:5–11). In every one of those cases, tsela means a whole side — a substantial structural element, not a small component.

The word in Genesis 2:21 is the plural form: mitssal'otav (מִצַּלְעֹתָיו) — "one of his sides." God does not extract a small bone. He takes a whole side. The man does not lose a rib — he loses half of himself.

And what God takes, he doesn't reshape from a wound. He builds (וַיִּבֶן, vayiven, H1129) it into a woman. The verb banah is the standard word for constructing significant structures — including the temple (1 Kings 6:2). God is not patching Adam's wound. He is constructing a corresponding being from the man's own substance.

When Adam wakes up, he doesn't simply admire the woman. He makes a declaration:

זֹאת הַפַּעַם עֶצֶם מֵעֲצָמַי וּבָשָׂר מִבְּשָׂרִי

"This at last is bone of my bones and flesh of my flesh." — Genesis 2:23

That phrase — "bone of my bones and flesh of my flesh" — is not a love poem. It is a covenant-recognition formula. The same words appear three more times in the Old Testament: Genesis 29:14, Judges 9:2, and 2 Samuel 5:1. Every time, they inaugurate a covenant bond. When Adam speaks these words, he is declaring covenant union, not expressing affection. The narrator confirms it immediately: "Therefore a man shall leave his father and his mother and cleave to his wife" (Genesis 2:24).

The implication of the tsela reading is significant. If the woman is built from the man's whole side, she is not a byproduct. She is the completion of what the man was incomplete without — built from his own substance, structurally parallel to him, the ezer kenegdo ("help corresponding to him," Genesis 2:18) who faces him and corresponds to him in every way.
