Ecclesiastes Chapter 2 Verse 10And whatsoever mine eyes desired I kept not from them, I withheld not my heart from any joy; for my heart rejoiced in all my labour: and this was my portion of all my labour.

For in much wisdom [is] much grief: and he that increaseth knowledge increaseth sorrow.

I said in mine heart, Go to now, I will prove thee with mirth, therefore enjoy pleasure: and, behold, this also [is] vanity.

I said of laughter, [It is] mad: and of mirth, What doeth it?

I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what [was] that good for the sons of men, which they should do under the heaven all the days of their life.

I made me great works; I builded me houses; I planted me vineyards:

I made me gardens and orchards, and I planted trees in them of all [kind of] fruits:

I made me pools of water, to water therewith the wood that bringeth forth trees:

I got [me] servants and maidens, and had servants born in my house; also I had great possessions of great and small cattle above all that were in Jerusalem before me:

I gathered me also silver and gold, and the peculiar treasure of kings and of the provinces: I gat me men singers and women singers, and the delights of the sons of men, [as] musical instruments, and that of all sorts.

So I was great, and increased more than all that were before me in Jerusalem: also my wisdom remained with me.

Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all [was] vanity and vexation of spirit, and [there was] no profit under the sun.

And I turned myself to behold wisdom, and madness, and folly: for what [can] the man [do] that cometh after the king? [even] that which hath been already done.

Then I saw that wisdom excelleth folly, as far as light excelleth darkness.

The wise man's eyes [are] in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.

Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also [is] vanity.

For [there is] no remembrance of the wise more than of the fool for ever; seeing that which now [is] in the days to come shall all be forgotten. And how dieth the wise [man]? as the fool.

Therefore I hated life; because the work that is wrought under the sun [is] grievous unto me: for all [is] vanity and vexation of spirit.

Yea, I hated all my labour which I had taken under the sun: because I should leave it unto the man that shall be after me.

And who knoweth whether he shall be a wise [man] or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This [is] also vanity.

Therefore I went about to cause my heart to despair of all the labour which I took under the sun.
