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

What is crooked cannot be made straight; and that lacking cannot be numbered.

Then I looked at 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, further, though a wise one speaks of knowing, yet he shall not be able to find it.
