All the major modern lexica (BDB 429; HALOT; DCH 4; Gesenius 18; NIDOTTE #3697) list יקע as a single lemma, glossing the Qal be dislocated, torn away, alienated and the Hiphil expose, impale, hang up (with the Hophal participle at 2 Samuel 21:13 be exposed/impaled). A common but mistaken claim that BDB splits the verb into two homonyms confuses its adjacent entry for the phonologically related נקע. The base etymology is Arabic waqaʿa (fall down, throw down), with Geʿez waqʿa and Jewish Aramaic/Mishnaic יקע/נקע (be dislocated) as further reflexes; HALOT's proposed Akkadian waqāʿu (impale) is contested and absent from CAD. The fullest philological study of the Hiphil is Robert Polzin, HTR 62 (1969): 227-240, who unifies the root and reads the Hiphil as a technical term for the solemn covenantal execution of oath-breakers, done before YHWH as covenant guarantor at both Baal-Peor (Numbers 25) and the Gibeonite reckoning (2 Samuel 21). Genuine disagreement runs along four lines. First, how tightly the Hiphil binds to the Qal: unifiers (Speiser, Genesis AB, 253-256; Polzin) derive the causative from the physical wrench, while Ben-Yehuda (Millon 4:2133) posited two unrelated stems and Haran treats the Hiphil as functionally independent ritual-legal vocabulary. Second, the concrete referent of the Hiphil: impalement (Milgrom; Levine; Chavel, JBL 122 [2003]: 23-52), post-mortem exposure (Ashley; Anderson; Gray), dismemberment (Cazelles, PEQ 1955; McCarter, II Samuel AB), crucifixion-like suspension (Targum, Vulgate, Josephus; traced in the reception history by Halperin, JJS 32 [1981]: 32-46), or the now-abandoned hurl-from-a-rock of W. Robertson Smith. Third, the theology: a broad sacrificial-expiatory consensus (the phrase before the LORD read as a propitiatory marker, blood-guilt and land pollution the framework) against Westbrook's strictly judicial-talionic reading (Studies in Biblical and Cuneiform Law, 1988, 47-55). Fourth, the register of the Qal in the prophets: physical wrench (Holladay, Jeremiah 1, Hermeneia, 211-213), visceral revulsion (Zimmerli, Ezekiel 1, Hermeneia, 481-491; Greenberg, Ezekiel 21-37, AB, 476-491; Block, Ezekiel 1-24, NICOT, 738-756; Lundbom, Jeremiah 1-20, AB, 419-422), or relational estrangement (older versions). Commentators are near-unanimous that the marital-emotive idiom of Jeremiah and Ezekiel and the execution Hiphil are functionally distinct in the biblical writers' usage even if they share one root, a caution consonant with James Barr's warnings about the root fallacy.
