רבינו בחיי — ויקחו לי תרומה

Q — Why does the parsha mention "תרומה" three times in two pesukim — "ויקחו לי תרומה... תקחו את תרומתי... וזאת התרומה"?

A — Rabbeinu Bachya notes that this is no rhetorical flourish — it is structural. The Mishkan is שקול כנגד בריאת העולם, the Mishkan equals creation. And creation itself was constituted by three primal forces: ה' בחכמה יסד ארץ, כונן שמים בתבונה, בדעתו תהומות נבקעו — chochmah, tevunah, da'as. The same triad reappears in the very pasuk that empowers Betzalel: "ואמלא אותו רוח אלהים בחכמה ובתבונה ובדעת" — for which the gemara already says he knew how to combine the letters with which heaven and earth were made. So three terumos are the human echo of the three forces by which the universe was raised up. Israel's terumah is not a metaphor for creation; it is a structural replication of it.
