The lexica are unanimous on the gloss and on the profile: BDB lists the verb as "slay (in poetry and late)," citing all three attested forms (Job 13:15, with God as subject; Job 24:14; Psalm 139:19, of God); Gesenius calls it "a poetic word" and suggests an underlying idea of cutting; HALOT and DCH treat the same three occurrences, with DCH adding the post biblical attestations within its expanded corpus. NIDOTTE places it in the semantic field of killing alongside הרג, מות in its causative use, רצח, טבח, שחט, and חלל, where its rarity, not any special nuance, is what distinguishes it. Comparative evidence shows q-t-l as a genuine West Semitic root for killing (Arabic qatala, Aramaic and Syriac qtal, Geez qatala, Sabaean qtl, with the original middle t preserved in Arabic and Sabaean and shifted to the emphatic consonant in Hebrew and Aramaic), while Akkadian has no cognate and uses daku instead; within Canaanite generally, including Moabite, הרג is the ordinary verb, so Hebrew's marginalization of q-t-l is the regional norm rather than an anomaly. The central scholarly question is therefore diachronic: Wagner's 1966 catalog of Aramaisms and Hurvitz's criteria treat the verb as a candidate Aramaism, though Hurvitz himself distinguished chronologically neutral Aramaisms from genuinely late ones and floated the alternative that Wisdom literature's Aramaic coloring reflects a Transjordanian or eastern literary setting (Kaufman's style switching); Young, Rezetko, and Ehrensvard reply that Aramaisms cannot date a text at all, since Hebrew and Aramaic were in contact throughout the biblical period and Aramaic looking forms are unstable in transmission. Hendel and Joosten defend a moderated position in which real diachronic change is detectable but no single feature proves much. Psalm 139 is often dated post exilic on a cluster of such features, of which this verb is one, but the evidence is conceded to be far from decisive. The interpretive drama at Job 13:15 concerns not the verb but the adjacent particle: the written consonants give the negative and the reading tradition gives "in him," producing either the defiant "he will slay me; I have no hope" or the pious "though he slay me, yet will I hope in him"; the Vulgate, Syriac, Targum, and a number of medieval Hebrew manuscripts read "in him," while the trend among modern Job commentators favors the negative, Seow noting that the verb rendered "hope" elsewhere in Job's speeches concerns waiting for the relief death brings. The Qumran Job fragments do not preserve the verse. The Old Greek of Job, roughly a sixth shorter than the Hebrew and often free, does not render the verb with a normal killing word at 13:15 and restructures 24:14, while Psalm 138:19 in the Greek uses the ordinary apokteino. A final note of reception history: this three times verb became the paradigm root of modern Semitic philology, because its consonants are strong, non guttural, and free of the softening that affects other letters, displacing the older model verb inherited from the medieval Jewish grammarians and their Arabic models; the Syriac grammatical tradition had already used it, since it is the ordinary Syriac word for killing. In Rabbinic Hebrew the root becomes fully productive again for killing and capital punishment, a lexical revival under Aramaic influence of the kind Segal acknowledged even while arguing for Mishnaic Hebrew's morphological independence.
