The classical lexica disagree on whether there is one lemma or two: BDB splits a primary noun parash I "horse, steed" (a rarer synonym of sus) from a derived nomen professionis parash II "horseman" (reconstructed as a qattal-form */parras/), while HALOT, DCH, and Gesenius-18 treat a single polysemous lexeme glossed "team/chariot-horse; horseman." The cognate set is Common Semitic and rich on the animal side (Arabic faras "horse" vs. faris "horseman"; Sabaic, Qatabanic, Geez, Modern South Arabian), with Militarev and Kogan reconstructing Proto-Semitic *paras- "horse"; the rider sense dominates in Aramaic and Syriac parrasa, matching BDB's geminate reconstruction. Modern lexicography and military history (Ap-Thomas 1970; Cantrell 2011; Yadin; Littauer and Crouwel; Drews; Dezso) converge on a diachronic reading: organized cavalry did not exist in the region before roughly 900 BCE, so in Pentateuchal, Solomonic, and early-monarchic texts the word denotes a chariot-horse or chariot crewman, with the 1 Kings 10:26 ratio of about 8.5 parashim per chariot decisive against a cavalry reading (so Cogan AB, Mulder HCOT, Sweeney OTL); only from the late eighth century (Assyrian, Babylonian, Persian armies) does it denote a mounted soldier. Egyptologists (Spalinger, Hoffmeier) and the Kurkh Monolith confirm the absence of cavalry behind the Exodus and ninth-century Israelite material. The animal reading is exegetically forced where the word stands beside other animals or in animal similes (Joel 2:4; Ezek 27:14; Isa 28:28, 31:1), and the LXX itself oscillates among hippeus "horseman," anabates "mounter/rider," and hippos "horse" (Isa 31:1; Josh 24:6). The verb parash "to separate, declare" (H6567) and the noun peresh "dung" (H6569) share the consonants but are coincidental homographs, not derivationally related; the older folk-etymology deriving the cavalry noun from "to separate" is rejected by BDB, HALOT, DCH, Gesenius-18, and TDOT, and the ancient versions render the three words in three separate lexical fields.
