Gesenius' Hebrew Grammar/56. Quadriliterals
On the origin of these altogether secondary formations cf. §30p. While quadriliteral nouns are tolerably numerous, only the following examples of the verb occur: (a) On the analogy of Piʿēl: כִּרְסֵם imperfect, יְכַרְסְמֶ֫נָּה, ψ 8014 from כָּסַם, cf. גָּזַם. Passive רֻֽטֲפַשׁ, Jb 3325. Participle מְכֻרְבָּל (cf. Aramaic כְּבַל), 1 Ch 1527. It is usual also to include among the quadriliterals פַּרְשֵׁז Jb 269, as a perfect of Aramaic form with Pathaḥ not attenuated. It is more correctly, however, regarded, with Delitzsch, as the infinitive absolute of a Piʿlel formation, from פָּרַשׂ, with euphonic change of the first שׂ to שׁ, and the second to ז. Moreover, the reading פַּרְשֵׂז also is very well attested, and is adopted by Beer in the text of Job; cf. the Rem. on p. 48 of his edition.
