ecc 2:1(Ecc. 2:1-26)
I said . . . heart-- (Luk 12:19).
thee--my heart, I will test whether thou canst find that solid good in pleasure which was not in "worldly wisdom." But this also proves to be "vanity" (Isa 50:11).
ecc 2:2laughter--including prosperity, and joy in general (Job 8:21).
mad--that is, when made the chief good; it is harmless in its proper place.
What doeth it?--Of what avail is it in giving solid good? (Ecc 7:6; Pro 14:13).
ecc 2:3Illustration more at large of Ecc 2:1-2.
I sought--I resolved, after search into many plans.
give myself unto wine--literally, "to draw my flesh," or "body to wine" (including all banquetings). Image from a captive drawn after a chariot in triumph (Rom 6:16, Rom 6:19; Co1 12:2); or, one "allured" (Pe2 2:18-19).
yet acquainting . . . wisdom--literally, "and my heart (still) was behaving, or guiding itself," with wisdom [GESENIUS]. MAURER translates: "was weary of (worldly) wisdom." But the end of Ecc 2:9 confirms English Version.
folly--namely, pleasures of the flesh, termed "mad," Ecc 2:2.
all the days, &c.--(See Margin and Ecc 6:12; Job 15:20).
ecc 2:4(Kg1 7:1-8; Kg1 9:1, Kg1 9:19; Kg1 10:18, &c.).
vineyards-- (Sol 8:11).
ecc 2:5gardens--Hebrew, "paradises," a foreign word; Sanskrit, "a place enclosed with a wall"; Armenian and Arabic, "a pleasure ground with flowers and shrubs near the king's house, or castle." An earthly paradise can never make up for the want of the heavenly (Rev 2:7).
ecc 2:6pools--artificial, for irrigating the soil (Gen 2:10; Neh 2:14; Isa 1:30). Three such reservoirs are still found, called Solomon's cisterns, a mile and a half from Jerusalem.
wood that bringeth forth--rather, "the grove that flourisheth with trees" [LOWTH].
ecc 2:7born in my house--These were esteemed more trustworthy servants than those bought (Gen 14:14; Gen 15:2-3; Gen 17:12-13, Gen 17:27; Jer 2:14), called "songs of one's handmaid" (Exo 23:12; compare Gen 12:16; Job 1:3).
ecc 2:8(Kg1 10:27; Ch2 1:15; Ch2 9:20).
peculiar treasure of kings and . . . provinces--contributed by them, as tributary to him (Kg1 4:21, Kg1 4:24); a poor substitute for the wisdom whose "gain is better than fine gold" (Pro 3:14-15).
singers--so David (Sa2 19:35).
musical instruments . . . of all sorts--introduced at banquets (Isa 5:12; Amo 6:5-6); rather, "a princess and princesses," from an Arabic root. One regular wife, or queen (Est 1:9); Pharaoh's daughter (Kg1 3:1); other secondary wives, "princesses," distinct from the "concubines" (Kg1 11:3; Psa 45:10; Sol 6:8) [WEISS, GESENIUS]. Had these been omitted, the enumeration would be incomplete.
ecc 2:9great--opulent (Gen 24:35; Job 1:3; see Kg1 10:23).
remained-- (Ecc 2:3).
ecc 2:10my labour--in procuring pleasures.
this--evanescent "joy" was my only "portion out of all my labor" (Ecc 3:22; Ecc 5:18; Ecc 9:9; Kg1 10:5).
ecc 2:11But all these I felt were only "vanity," and of "no profit" as to the chief good. "Wisdom" (worldly common sense, sagacity), which still "remained with me" (Ecc 2:9), showed me that these could not give solid happiness.
ecc 2:12He had tried (worldly) wisdom (Ecc 1:12-18) and folly (foolish pleasure) (Ecc 2:1-11); he now compares them (Ecc 2:12) and finds that while (worldly)
wisdom excelleth folly (Ecc 2:13-14), yet the one event, death, befalls both (Ecc 2:14-16), and that thus the wealth acquired by the wise man's "labor" may descend to a "fool" that hath not labored (Ecc 2:18-19, Ecc 2:21); therefore all his labor is vanity (Ecc 2:22-23).
what can the man do . . . already done-- (Ecc 1:9). Parenthetical. A future investigator can strike nothing out "new," so as to draw a different conclusion from what I draw by comparing "wisdom and madness." HOLDEN, with less ellipsis, translates, "What, O man, shall come after the king?" &c. Better, GROTIUS, "What man can come after (compete with) the king in the things which are done?" None ever can have the same means of testing what all earthly things can do towards satisfying the soul; namely, worldly wisdom, science, riches, power, longevity, all combined.
ecc 2:13(Pro 17:24). The worldly "wise" man has good sense in managing his affairs, skill and taste in building and planting, and keeps within safe and respectable bounds in pleasure, while the "fool" is wanting in these respects ("darkness," equivalent to fatal error, blind infatuation), yet one event, death, happens to both (Job 21:26).
ecc 2:15why was I--so anxious to become, &c. (Ch2 1:10).
Then--Since such is the case.
this--namely, pursuit of (worldly) wisdom; it can never fill the place of the true wisdom (Job 28:28; Jer 8:9).
ecc 2:16remembrance--a great aim of the worldly (Gen 11:4). The righteous alone attain it (Psa 112:6; Pro 10:7).
for ever--no perpetual memorial.
that which now is--MAURER, "In the days to come all things shall be now long ago forgotten."
ecc 2:17Disappointed in one experiment after another, he is weary of life. The backslider ought to have rather reasoned as the prodigal (Hos 2:6-7; Luk 15:17-18).
grievous unto me-- (Job 10:1).
ecc 2:18One hope alone was left to the disappointed worldling, the perpetuation of his name and riches, laboriously gathered, through his successor. For selfishness is mostly at the root of worldly parents' alleged providence for their children. But now the remembrance of how he himself, the piously reared child of David, had disregarded his father's dying charge (Ch1 28:9), suggested the sad misgivings as to what Rehoboam, his son by an idolatrous Ammonitess, Naamah, should prove to be; a foreboding too fully realized (1Ki. 12:1-18; Kg1 14:21-31).
ecc 2:20I gave up as desperate all hope of solid fruit from my labor.
ecc 2:21Suppose "there is a man," &c.
equity--rather "with success," as the Hebrew is rendered (Ecc 11:6), "prosper," though Margin gives "right" [HOLDEN and MAURER].
evil--not in itself, for this is the ordinary course of things, but "evil," as regards the chief good, that one should have toiled so fruitlessly.
ecc 2:22Same sentiment as in Ecc 2:21, interrogatively.
ecc 2:23The only fruit he has is, not only sorrows in his days, but all his days are sorrows, and his travail (not only has griefs connected with it, but is itself), grief.
ecc 2:24English Version gives a seemingly Epicurean sense, contrary to the general scope. The Hebrew, literally is, "It is not good for man that he should eat," &c., "and should make his soul see good" (or "show his soul, that is, himself, happy"), &c. [WEISS]. According to HOLDEN and WEISS, Ecc 3:12, Ecc 3:22 differ from this verse in the text and meaning; here he means, "It is not good that a man should feast himself, and falsely make as though his soul were happy"; he thus refers to a false pretending of happiness acquired by and for one's self; in Ecc 3:12, Ecc 3:22; Ecc 5:18-19, to real seeing, or finding pleasure when God gives it. There it is said to be good for a man to enjoy with satisfaction and thankfulness the blessings which God gives; here it is said not to be good to take an unreal pleasure to one's self by feasting, &c.
This also I saw--I perceived by experience that good (real pleasure) is not to be taken at will, but comes only from the hand of God [WEISS] (Psa 4:6; Isa 57:19-21). Or as HOLDEN, "It is the appointment from the hand of God, that the sensualist has no solid satisfaction" (good).
ecc 2:25hasten--after indulgences (Pro 7:23; Pro 19:2), eagerly pursue such enjoyments. None can compete with me in this. If I, then, with all my opportunities of enjoyment, failed utterly to obtain solid pleasure of my own making, apart from God, who else can? God mercifully spares His children the sad experiment which Solomon made, by denying them the goods which they often desire. He gives them the fruits of Solomon's experience, without their paying the dear price at which Solomon bought it.
ecc 2:26True, literally, in the Jewish theocracy; and in some measure in all ages (Job 27:16-17; Pro 13:22; Pro 28:8). Though the retribution be not so visible and immediate now as then, it is no less real. Happiness even here is more truly the portion of the godly (Psa 84:11; Mat 5:5; Mar 10:29-30; Rom 8:28; Ti1 4:8).
that he--the sinner
may give--that is, unconsciously and in spite of himself. The godly Solomon had satisfaction in his riches and wisdom, when God gave them (Ch2 1:11-12). The backsliding Solomon had no happiness when he sought it in them apart from God; and the riches which he heaped up became the prey of Shishak (Ch2 12:9).
Earthly pursuits are no doubt lawful in their proper time and order (Ecc 3:1-8), but unprofitable when out of time and place; as for instance, when pursued as the solid and chief good (Ecc 3:9-10); whereas God makes everything beautiful in its season, which man obscurely comprehends (Ecc 3:11). God allows man to enjoy moderately and virtuously His earthly gifts (Ecc 3:12-13). What consoles us amidst the instability of earthly blessings is, God's counsels are immutable (Ecc 3:14).
