The following is suggested as the most satisfactory rendering of these verses: Time (literally, a year; but the root-idea is the repetition or change of the seasons) carries them away with its flood; they are in the morning like grass sprouting; in the morning it flourishes and sprouts, in the evening it is cut down and withered.
This is obtained by taking the verb as third feminine instead of second masculine, and slightly changing the vowels of the noun rendered in Authorised Version sleep. The confusion of the metaphor is thus avoided, and immediately on the mention of the stream of time is suggested the image of the vegetation springing into life at the first touch of rain, and dying in a day — an image so natural to an Oriental. The verb, carries away with its floods is found only here and in Psalms 77:17 (“the clouds poured out water”), but the cognate noun is frequent for a heavy rainfall (Isaiah 4:6, &c.), such as in the East in a few moments causes a flood. This interpretation is partly supported by the LXX. and Vulg.: “Their years shall be nothingness;” and many commentators have felt that the image of the “stream of time” was required here. For the rendering cut down, comp. Job 24:24. Some prefer “fades.” The general force of the figure is the same whether we think of the generations dropping away like withered grass or cut down and dried like hay.
