Hasteth - literally, at his place panting (in his eagerness) riseth he there.

These verses are confused by being falsely divided. The first clause of the sixth should be joined to the fifth verse.
"The sun also ariseth, and the sun goeth down, and hasteth to his place where he ariseth; going to the south, and circulating to the north."

The sun also ariseth, and the sun goeth down, and hasteth to his place where he arose. The sun rises in the morning and sets at evening in our hemisphere, according to the appearance of things; and then it makes haste to go round the other hemisphere in the night: it "pants", as the word (t) signifies; the same figure is used by other writers (u); like a man out of breath with running; so this glorious body, which rejoiceth as a strong man to run his race, and whose circuit is from one end of the heavens to the other, Psalm 19:5; is in haste to get to the place where he rose in the morning, and there he makes no stop, but pursues his course in the same track again. By this instance is exemplified the succession of the generations of men one after another, as the rising and setting of the sun continually follows each other; and also sets forth the restless state of things in the world, which, like the sun, are never at a stand, but always moving, and swiftly taking their course; and likewise the changeable state of man, who, like the rising sun, and when at noon day, is in flourishing circumstances, and in the height of prosperity, but as this declines and sets, so he has his declining times and days of adversity. Moreover, like the rising sun, he comes into this world and appears for a while, and then, like the setting sun, he dies; only with this difference, in which the sun has the preference to him, as the earth before had; the sun hastens and comes to its place from whence it arose, but man lies down and rises not again till the heavens be no more, and never returns to his place in this world, that knows him no more, Job 7:10. The Jews (w) say, before the sun of one righteous, man sets, the sun of another righteous man rises.

(Psalm 19:5-6). "Panting" as the Hebrew for "hasteth"; metaphor, from a runner (Psalm 19:5, "a strong man") in a "race." It applies rather to the rising sun, which seems laboriously to mount up to the meridian, than to the setting sun; the accents too favor MAURER, "And (that too, returning) to his place, where panting he riseth."

"And the sun ariseth, the sun goeth down, and it hasteth (back) to its place, there to rise again." It rises and sets again, but its setting is not a coming to rest; for from its place of resting in the west it must rise again in the morning in the east, hastening to fulfil its course. Thus Hitzig rightly, for he takes "there to rise again" as a relative clause; the words may be thus translated, but strictly taken, both participles stand on the same level; שׁואף (panting, hastening) is like בּא in Ecclesiastes 1:4, the expression of the present, and זו that of the fut. instans: ibi (rursus) oriturus; the accentuation also treats the two partic. as co-ordinate, for Tiphcha separates more than Tebir; but it is inappropriate that it gives to ואל־ם the greater disjunctive Zakef Quaton (with Kadma going before). Ewald adopts this sequence of the accents, for he explains: the sun goes down, and that to its own place, viz., hastening back to it just by its going down, where, panting, it again ascends. But that the sun goes down to the place of its ascending, is a distorted thought. If "to its place" belongs to "goeth," then it can refer only to the place of the going down, as e.g., Benjamin el-Nahawendi (Neubauer, Aus der Petersb. Bibl. p. 108) explains: "and that to its place," viz., the place of the going down appointed for it by the Creator, with reference to Psalm 104:19, "the sun knoweth his going down." But the שׁם, which refers back to "its place," opposes this interpretation; and the phrase שׁו cannot mean "panting, rising," since שאף in itself does not signify to pant, but to snatch at, to long eagerly after anything, thus to strive, panting after it (cf. Job 7:2; Psalm 119:131), which accords with the words "to its place," but not with the act of rising. And how unnatural to think of the rising sun, which gives the impression of renewed youth, as panting! No, the panting is said of the sun that has set, which, during the night, and thus without rest by day and night, must turn itself back again to the east (Psalm 19:7), there anew to commence its daily course. Thus also Rashi, the lxx, Syr., Targ., Jerome, Venet., and Luther. Instead of שׁו, Grtz would read שׁב אף, redit (atque) etiam; but שׁו is as characteristic of the Preacher's manner of viewing the world as סובב וגו, Ecclesiastes 1:6, and ין, Ecclesiastes 1:8. Thus much regarding the sun. Many old interpreters, recently Grtz, and among translators certainly the lxx, refer also Ecclesiastes 1:6 to the sun. The Targ. paraphrases the whole verse of the state of the sun by day and night, and at the spring and autumn equinox, according to which Rashi translates הרוּח, la volont (du soleil). But along with the sun, the wind is also referred to as a third example of restless motion always renewing itself. The division of the verses is correct; Ecclesiastes 1:6 used of the sun would overload the figure, and the whole of Ecclesiastes 1:6 therefore refers to the wind.

The sun - The sun is in perpetual motion, rising, setting, and rising again, and so constantly repeating its course in all succeeding days, and years, and ages; and the like he observes concerning the winds and rivers, Ecclesiastes 1:6-7, and the design of these similitudes seem to be; to shew the vanity of all worldly things, and that man's mind can never be satisfied with them, because there is nothing in the world but a constant repetition of the same things, which is so irksome, that the consideration thereof hath made some persons weary of their lives; and there is no new thing under the sun, as is added in the foot of the account, Ecclesiastes 1:9, which seems to be given us as a key to understand the meaning of the foregoing passages. And this is certain from experience that the things of this world are so narrow, and the mind of man so vast, that there must be something new to satisfy the mind; and even delightful things by too frequent repetition, are so far from yielding satisfaction, that they grow tedious and troublesome.
