▼Saadia, who renders the גּלגּל in Psa 77:19 as an astronomical expression with Arab. 'l - frk, the sphere of the heavens, here has professedly Arab. kâlgrâblt, which would be a plural from expanded out of Arab. grâbı̂l, “sieves” or “tambourines;” it is, however, to be read, as in Isa 17:13, Codex Oxon., Arab. kâlgirbâlt. The verb Arab. garbala, “to sift,” is transferred to the wind, e.g., in Mutanabbi (edited with Wahidi’s commentary by Dieterici), p. 29, l. 5 and 6: “it is as though the dust of this region, when the winds chase one another therein, were sifted,” Arab. mugarbalu (i.e., caught up and whirled round); and with other notional and constructional applications in Makkarı̂, i. p. 102, l. 18: “it is as though its soil had been cleansed from dust by sifting,” Arab. gurbilat (i.e., the dust thereof swept away by a whirlwind). Accordingly Arab. girbâlat signifies first, as a nom. vicis, a whirling about (of dust by the wind), then in a concrete sense a whirlwind, as Saadia uses it, inasmuch as he makes use of it twice for גּלגּל. So Fleischer in opposition to Ewald, who renders “like the sweepings or rubbish.”
