1 tn Heb “are going” or “are walking.” The term הֹלְכִים (holÿkhim, Qal active participle masculine plural from הָלַךְ, halakh,“to walk”) emphasizes continual, durative, uninterrupted action (present universal use of participle). This may be an example of personification; this verb is normally used in reference to the human activity of walking. Qoheleth compares the flowing of river waters to the action of walking to draw out the comparison between the actions of man (1:4) and the actions of nature (1:5-11).
2 tn Heb “there they are returning to go.” The term שָׁבִים (shavim, Qal active participle masculine plural from שׁוּב, shuv, “to return”) emphasizes the continual, durative action of the waters. The root שׁוּב is repeated in 1:6-7 to emphasize that everything in nature (e.g., wind and water) continually repeats its actions. For all of the repetition of the cycles of nature, nothing changes; all the constant motion produces nothing new.
sn This verse does not refer to the cycle of evaporation or the return of water by underground streams, as sometimes suggested. Rather, it describes the constant flow of river waters to the sea. For all the action of the water – endless repetition and water constantly in motion – there is nothing new accomplished.
