Ecclesiastes 2:11, 15, 17, 19, 21, 23, 26

Then I looked on all the works that my hands had done And on the labor in which I had toiled; And indeed all was vanity and grasping for the wind. There was no profit under the sun.

So I said in my heart, “As it happens to the fool, It also happens to me, And why was I then more wise?” Then I said in my heart, “This also is vanity.”

Therefore I hated life because the work that was done under the sun was distressing to me, for all is vanity and grasping for the wind.

And who knows whether he will be wise or a fool? Yet he will rule over all my labor in which I toiled and in which I have shown myself wise under the sun. This also is vanity.

For there is a man whose labor is with wisdom, knowledge, and skill; yet he must leave his heritage to a man who has not labored for it. This also is vanity and a great evil.

For all his days are sorrowful, and his work burdensome; even in the night his heart takes no rest. This also is vanity.

For God gives wisdom and knowledge and joy to a man who is good in His sight; but to the sinner He gives the work of gathering and collecting, that he may give to him who is good before God. This also is vanity and grasping for the wind.
