41 The relative pronoun introduces the verse as a relative clause, working with the “godless person” of the preceding verse. The relative pronoun is joined to the resumptive pronoun in the translation: “who + his trust” = “whose trust.”
42 The noun כֶּסֶל (kesel) in this half of the verse must correspond to “his security” in the second half. The meaning must be “his trust” (see 4:6). The two words will again be parallel in 31:24.
43 The word יָקוֹט (yaqot) is not known anywhere else; here it looks like it should be a noun to parallel “spider’s house” in the next colon. But scholars have tried to identify it as a verb, perhaps an imperfect of קוֹט (qot, 876 ), or related to an Arabic qatta, “to cut.” Some versions have “break in sunder” (, ); others “cut off” (). Apart from verbs, some commentators follow Sa`adia’s Arabic translation “sun cords,” meaning “gossamer.” Accordingly, there are emendations like “threads,” “threads of summer,” “spider threads,” and the like. D. J. A. Clines agrees with those who conclude that emendations based on Sa`adia’s translation lack a sound philological basis. E. Dhorme “somewhat timidly” suggests יַלְקוּט (yalqut), the shepherd’s bag or scrip (1 Sam 17:40). He suggests that an empty bag would be a symbol of something unstable and futile. It seems impossible to determine exactly what the word meant. One can only conclude that it means something like “fragile” or “futile.” The is of no help: “for his house shall be without inhabitants.”
44 The second half of the verse is very clear. What the godless person relies on for security is as fragile as a spider’s web—he may as well have nothing. The people of the Middle East view the spider’s web as the frailest of all “houses.”
45 The verb עָמַד (’amad, “to stand”) is almost synonymous with the parallel קוּם (qum, “to rise; to stand”). The distinction is that the former means “to remain standing” (so it is translated here “hold up”), and the latter “rise, stand up.”
46 The idea is that he grabs hold of the house, not to hold it up, but to hold himself up or support himself. But it cannot support him. This idea applies to both the spider’s web and the false security of the pagan.
