The lexica speak with one voice on the core sense and diverge only on nuance. BDB (836) glosses "cord, thread" with the qualifier "twisted" and sorts the eleven occurrences into functional groups (seal cord, simile cord, measuring line, the blue fastening cord, Num 19:15, the gold threads of Exod 39:3). HALOT gives the fuller range "cord, thread, string, wire; ribbon" and derives the noun from the root פתל on the passive-adjectival qatil pattern. DCH VI, 810 to 811, collects the widest set of glosses ("cord, thread, string, lace, wire, ribbon, tie") and extends the attestation beyond the Hebrew Bible to 1QM 5:6, 9, 14 and to fragmentary Ben Sira readings. Gesenius 18 renders "Schnur, Faden, Band, Kordel" and glosses the formation as "das Gedrehte," the twisted thing. The root is one of the more secure pan-Semitic items: Akkadian patalu "to twist" with the derived noun pitiltu "twisted cord" (CAD P, 275 to 277 and 438 to 439; AHw II, 847), Arabic fatala with the noun fatil (Lane VI, 2333), Aramaic and Syriac petila (Payne Smith, cols. 3316 to 3317; Sokoloff, DJPA 452), Ge'ez fatala (Leslau, 170 to 171), Sabaic ftl (Biella, 411), and a broken Ugaritic ptlt (DULAT). Only Hebrew develops the moral extension of the root, "crooked, crafty," at Job 5:13, Prov 8:8, and Deut 32:5. On Genesis 38 the commentators are uniform in reading the pledge triad as a portable identity kit with this noun as the cylinder seal's neck cord (Sarna, JPS Genesis, 268; Wenham, WBC 2, 366 to 368; Hamilton, NICOT, 442 to 446; Waltke, 505 to 506), supported by Collon, First Impressions, 100 and 113 to 119, and confirmed by the Septuagint's choice of hormiskos, a small necklace. On the priestly fastening cords see Childs, OTL, 521 to 539; Propp, AB 2A, 430 to 447; Houtman, HCOT III, 484 to 489; Cassuto, 379 to 384. On Numbers 15:38 Milgrom ("Of Hems and Tassels," 1983, and JPS Numbers, Excursus 38, 410 to 414) argues from Mari legal texts and Mesopotamian iconography that the ornate hem marked status, so that requiring a blue cord on every Israelite's garment enacts Exod 19:6 materially; Levine (AB 4, 400 to 404) endorses this, while Wenham and Ashley foreground the mnemonic function instead, and the status reading should be labeled a thesis resting on comparative iconography rather than an explicit claim of the text. On Ezekiel 40:3 Zimmerli (Hermeneia, 346 to 347) identifies the flax cord plus the six-cubit reed as the standard surveyor's kit, compares Gudea Statue B, and notes that the cord itself is never used in the measurements that follow; Block (NICOT, 513 to 517) adds Egyptian rope-stretcher parallels. On Judges 16:9 Boling (AB 6A, 246 to 248) and Webb (NICOT, 400 to 402) both stress the contrast between fresh bowstrings and flammable flax waste. The Septuagint's eight distinct renderings across the eleven occurrences (hormiskos, klosma, stremma, kekloismene hyakinthos, hyakinthinos, loma, spartion oikodomon, and the verbal periphrasis desmon katadedetai) show that the word had not yet frozen into a technical term; Mishnaic Hebrew then specializes it three ways, as a lamp wick (Shabbat 2), as the blue thread of the tassel (Menachot 4:1), and as the sealed-vessel category of the purity laws (Kelim 10:1 to 2), a development Bar-Asher treats as continuous with the biblical formation.
