אבן עזרא — אדם כי ימות באהל / כל הבא אל האהל

Q — The Torah's archetypal corpse-impurity case is "אדם כי ימות באהל" — but most Jews live in houses, not tents. Why does the Torah use "אהל" as its paradigm?

A — Ibn Ezra makes a methodologically rich move. The same halacha applies to a house (with one structural distinction — a house, being attached to the ground, isn't itself susceptible to tum'ah). But the Torah uses the term most concrete to its original audience — the wilderness generation, who lived in tents. He cross-references the same construction in "אשר ישחט שור או כשב ועז במחנה" — the camp is the wilderness setting, but the halacha (issur shechutei chutz) clearly applies after entering the Land too. The deeper principle: Torah uses the language and concrete imagery of its first generation, while the halacha is "מיד ולדורות" — applicable both immediately and forever. Note: the Mishna in Ohalot has updated to "בית"; the halachic category-name "טומאת אהל" preserves the Torah's original term as a fixed designator even though the lived reality has shifted. Ramban endorsed this reading: "דבר הכתוב בהווה כי המצוה מיד ולדורות."
