BDB (828) glosses פַּס "flat of hand or foot (palm, sole)" and כְּתֹנֶת פַּסִּים "a tunic reaching to palms and soles," filing the noun under a root I. פסס compared with פשׂה "to spread"; Gesenius (Tregelles) derives it from פָּסַס as "extremity" and glosses the phrase "a tunic extending to the wrists and ankles, a long tunic with sleeves," invoking Josephus (Ant. VII.8.1) on the long-sleeved ankle-length tunics of royal virgins. HALOT lists three options (Speiser's ornamented tunic, with a question mark; a garment reaching wrists and ankles, with König, Zorell, Dalman and Müller; Albright's overlapping tablet-like layers, BA 36 [1973] 31f., citing Punic פס "tablet") but defaults to "long garment reaching to the extremities"; DCH registers three possible homonyms without adjudicating. The controlling comparative datum is Biblical Aramaic פַּס יְדָה "palm of the hand" at Daniel 5:5, 24 (so Collins, Hermeneia 1993; Goldingay, WBC; Hartman and Di Lella, AB 23, 1978), reinforced by Syriac passtā "palm, sole," Aramaic passā "tablet, flat surface" (Sokoloff, DJBA 901, DJPA 431), Phoenician פס "tablet" (DNWSI II.921) and rabbinic פִּסַּת הַיָּד / פִּסַּת הָרֶגֶל (Jastrow 1191; m. Ohalot 1:8); the shared semantic core is "flat spread-out surface," which suits palm, sole and tablet but not "many-colored." Tur-Sinai, in Ben-Yehuda, argues that the later Hebrew "stripe" sense is a loan rather than authentic Semitic, weakening the etymological base of the many-colored reading. Speiser (Genesis, AB 1, 1964, 289-290) dismissed both traditional renderings as "sheer guesses from the context" and proposed Akkadian pišannu, a term for appliqué ornaments known from the Eanna temple inventories published by Oppenheim (JNES 8 [1949] 172-193); Tawil (Akkadian Lexical Companion, 2009, 300) endorses the equation, but Oppenheim himself wrote that the meaning of the pišannu garment is not clear, and McCarter (II Samuel, AB 9, 1984, 318-319, 322-323) repudiated Speiser in the same series, observing that the Mesopotamian garment clothed a divine statue rather than a person and that passīm is plural, not dual, hence "gown extending to the extremities." That reading runs unbroken from Driver (Genesis, 1904, 322 n.3), Gunkel (1901) and Skinner (ICC, 1910, 444) through von Rad (OTL, 1972, 351), who located the many-colored rendering as a Septuagint interpretation preserved in the KJV. Dewrell (Biblica 97 [2016] 161-174) rejects Speiser and also Mendenhall's Ugaritic pḏ (refuted phonologically by Smith, Ugaritic Baal Cycle 1, 1994, 293-294), derives the noun from a root cognate to Akkadian pasāmu / paṣānu "to veil" (CAD P 217-218), compares Middle Assyrian Laws A 40-41 on veiling as the legal marker of respectable feminine status, and argues that the phrase is philologically original to 2 Samuel 13 and was secondarily inserted into Genesis 37, noting that bare כְּתֹנֶת stands at Gen 37:31, 33 while the full phrase clusters at 37:3, 23, 32. Bledstein (in Brenner, ed., Samuel and Kings: A Feminist Companion, 2000, 65-83) reads a flounced kaunakes-style priestess robe; Görg (BN 102 [2000] 9-13) proposed Egyptian pśy "dye," which Dewrell shows rests on silently deleted question marks in the Wörterbuch; Ugaritic lbš psm rq (CAT3 4.205:5) is glossed "veil, gauze(?)" by DULAT 685. Wenham (WBC 2, 1994, 351), Hamilton (NICOT, 1995, 407-409), Waltke, Sarna (JPS Genesis, 1989, 255), Westermann (CC, 1986) and Alter decline to adjudicate the philology while agreeing that the garment is a status marker, with the internal gloss at 2 Samuel 13:18 on the dress of the king's virgin daughters as the interpretive control and, as Sarna notes, as evidence that the phrase was already obscure to a biblical author; Noonan (in The Body: Lived, Cultured, Adorned, HUC Press, 2022, 319-360) is now the fullest dedicated treatment. The version split governs reception: Septuagint Genesis χιτῶνα ποικίλον against Septuagint Samuel χιτὼν καρπωτός (Lucianic ἀστραγαλωτός), with Aquila ἀστραγαλωτός and Symmachus χειριδωτός following the extremity route, and Vulgate tunicam polymitam at Gen 37:3 beside tunica talaris at 2 Samuel 13:18-19 and the hybrid tunica talari et polymita at Gen 37:23; the KJV "coat of many colours" descends through Wycliffe (1382) and Tyndale (1526) from the Genesis line alone.
