And I gave my heart to know wisdom and to know madness and folly; I have perceived that this also is striving of spirit.

For in much wisdom is much grief; and he who increases knowledge increases sorrow.

Then I looked on all the works that my hands had done, and on the labor that I had labored to do; and, behold, all was vanity and striving of spirit; and there was no profit under the sun.

Therefore I hated life; because the work that is done under the sun is evil to me; for all is vanity and striving of spirit.

For God gives wisdom, and knowledge, and joy to a man who is good in His sight. But to the sinner He gives labor, to collect and gather, that he may give to him who is good before God. This also is vanity and striving of spirit.

Thus Solomon's wisdom excelled the wisdom of all the sons of the East and all the wisdom of Egypt.

He spoke three thousand proverbs, and his songs were one thousand and five.

Behold, You have made my days as a handbreadth, and my age is as nothing before You. Surely every man, even though standing tall, is total vanity. Selah.

Surely every man walks about like a shadow! Surely they are stirred up in vain. He heaps up the produce, and does not know who shall gather it.
