שבלול (Shablul) — snail

Etymology

The word shablul is a biblical hapax legomenon, appearing only once in the Book of Psalms (58:9) in a cryptic verse comparing the wicked to a melting shablul. This ambiguity led the 2nd-century BCE translators of the Septuagint to mistranslate it as "wax" (keros), assuming a substance that melts. This error persisted in the Latin Vulgate and many subsequent translations. However, post-biblical Jewish texts like the Talmud indicate that the word remained in use in the Land of Israel, identifying it as a small creature used for medicinal purposes, specifically for treating stings.

In the 10th century, a linguistic debate emerged among medieval grammarians. One camp, including Saadia Gaon, linked shablul to the root Sh-B-L (as in shibboleth), interpreting it as a "water stream" or "torrent." The opposing camp, led by David Alfasi and Jonah ibn Janah, argued firmly that it referred to a snail or slug, citing the Talmudic usage. Ibn Ezra even suggested it might be a jellyfish. By the time of Rashi in the 11th century, the "snail" interpretation gained dominance, as he explicitly identified it with the Old French limace.

Modern linguistic analysis supports the "snail" identification through an internal Hebrew connection to the root B-L-L, which denotes winding or spiral shapes. This same root appears in the description of Solomon's Temple in the Book of Kings, referring to belulim—winding or spiral stairs. While the word chilazon (of Aramaic origin) was historically used for the sea snails used in dye production, shablul has become the standard modern Hebrew term for the common land snail.
