צָב (tsav) — turtle, tortoise

Etymology

The word צָב appears in the Hebrew Bible in Leviticus 11:29, in the list of ritually impure creeping creatures: "these are the impure among the crawling things that crawl on the ground: the weasel, the mouse, and the tsav according to its kind." But the tsav of the Bible was not a turtle. Based on cognate evidence — Arabic ḍabb and Syriac ʿabbā both refer to lizards — and the consistent understanding of early translators, the biblical tsav was a lizard.

This identification was preserved in early Jewish tradition. The Midrashic work Sifra (on Leviticus) describes the tsav as having "kinds": the spotted kind, the ben ha-nefilim, and the salamander — all lizard-like creatures. (The salamander is actually an amphibian, but the Sages did not know this distinction.) Ancient translators also rendered it as a lizard: the Greek Septuagint as krokodilos ho khersaios ("land crocodile"), Aramaic Targums as ḥardona (lizard), and Jerome's Latin Vulgate as crocodillus.

The meaning of צָב was lost after the last native Hebrew speakers died around the 2nd–3rd century CE. Subsequent interpreters had to reconstruct the word from context and analogy. In Arab lands, the Arabic cognate ḍabb (lizard) provided guidance, and medieval authorities like Jonah ibn Janah, the Karaite Levi ben Japheth, and Maimonides all correctly identified צָב as a lizard.

But in France, there was no Arabic. Rashi (Rabbi Solomon ben Isaac, 11th century) generated a different tradition: he glossed tsav as "froyet" — apparently an Old French word for toad, related to modern French crapaud — based on the word's sound and the animal's appearance. He elsewhere wrote that צָב is "boteril," an Italian/Provençal word for "small toad" (boterel). Rashi's students and the Ashkenazic tradition followed this identification.

A third interpretive tradition grew up in Byzantium. Tobiah ben Eliezer, in his commentary Lekah Tov, proposed that the tsav was "the creeping thing that is covered like a goblet" — identifying it with the shell-bearing reptile we know as a turtle. He drew on a second, unrelated biblical use of the same word: in Numbers 7:3 and Isaiah 66:20, tsav (plural tsavim) appears as a type of covered wagon or cart. This led him to associate the word with a covered or enclosed creature.

Into the modern period, two traditions competed: the tortoise interpretation (used, for example, by the educator Baruch Linda and by the poet Y.L. Gordon in his translation of Aesop's fable of the hare and the tortoise) and the toad interpretation (used by many German-influenced scholars, since German links the two creatures — Kröte is "toad" and Schildkröte is "armored toad" = tortoise). Many 19th- and early 20th-century Hebrew books called the toad "tsav" and the tortoise "tsav ha-shiryon" (armored tsav) or "tsav ha-magen" (shield tsav).

The zoologist Yisrael Aharoni attempted to introduce shalḥufa (from Arabic sulḥafāt) as the Hebrew word for tortoise, but only Bialik used it. The zoologist Yeshayahu Margolin standardized "karpada" (from Aramaic) for "toad" in the late 1930s (the word had been coined by Moshe Shulbaum in 1879, based on Aramaic karpedai plus French crapaud). The Hebrew Language Committee's 1936 ruling on reptile names finally separated the two creatures definitively: karpada for toad (frog-like), tsav for tortoise (armored). This distinction has held ever since, and no one today remembers that the biblical tsav was actually a lizard.
