Num 4:20 כּבלּע, “like a swallow, a gulp,” is probably a proverbial expression, according to the analogy of Job 7:19, for “a single instant,” of which the Arabic also furnishes examples (see A. Schultens on Job 7:19). The Sept. rendering, ἐξάπινα, conveys the actual sense. A historical illustration of Num 4:20 is furnished by 1Sa 6:19.
