Ecclesiastes 1:7

“All the rivers run into the sea; yet the sea [is] not full, etc.] Which flow from fountains or an formed by hasty rains; these make their way to the sea, yet the sea is not filled therewith, and made to abound and overflow the earth, as it might be expected it would. So Seneca saysf24 we wonder that the accession of rivers is not perceived in the sea; and Lucretiusf25 observes the same, that it is wondered at that the sea should not increase, when there is such a flow of waters to it from all quarters; besides the wandering showers and flying storms that fall into it, and yet scarce increased a drop; which he accounts for by the exhalations of the sun, by sweeping and drying winds, and by…”

“By subterraneous cavities, and by evaporation forming rain clouds, the fountains and rivers are supplied from the sea, into which they then flow back. The connection is: Individual men are continually changing, while the succession of the race continues; just as the sun, wind, and rivers are ever shifting about, while the cycle in which they move is invariable; they return to the point whence they set out. Hence is man, as in these objects of nature which are his analogue, with all the seeming changes "there is no new thing" (Ecc 1:9).”

“The place - i. e., The spring or river-head. It would seem that the ancient Hebrews regarded the clouds as the immediate feeders of the springs (Proverbs 8:28, and Psalms 104:10, Psalms 104:13). Genesis 2:6 indicates some acquaintance with the process and result of evaporation. return to 'Top of Page'”

“Is not full - So as to overflow the earth. Whereby also he intimates the emptiness of mens minds, notwithstanding all the abundance of creature comforts. Rivers come - Unto the earth in general, from whence they come or flow into the sea, and to which they return by the reflux of the sea. For he seems to speak of the visible and constant motion of the waters, both to the sea and from it, and then to it again in a perpetual reciprocation. Ecclesiastes 1:8”

“1:7-8 the sea is never full . . . we are never satisfied: This image introduces the unfulfilling nature of life.”

“the rivers run: Job 38:10, Job 38:11; Psa 104:6-9 return again: Heb. return to go Ecclesiastes 1:8”

“"All rivers run into the sea, and the sea becomes not full; to the place whence the rivers came, thither they always return again." Instead of nehhárim, nehhalim was preferred, because it is the more general name for flowing waters, brooks, and rivers; נחל (from נחל, cavare), אפיק (from אפק, continere), and (Arab.) wadin (from the root-idea of stretching, extending), all three denote the channel or bed, and then the water flowing in it. The sentence, "all rivers run into the sea," is consistent with fact. Manifestly the author does not mean that they all immediately flow thither; and by "the sea" he does not mean this or that sea; nor does he think, as the Targ. explains, of the earth as a…”
