All things are full of weariness; man cannot express it: the eye is not satisfied with seeing, nor the ear filled with hearing.

That which is crooked cannot be made straight: and that which is lacking cannot be numbered.

I made myself gardens and orchards, and I planted trees in them with all kind of fruit:

Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labors to seek it out, yet he shall not find it; yea moreover; though a wise man thinks to know it, yet shall he not be able to find it.

A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?
