All things are full of labour; man cannot utter 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 wanting cannot be numbered.

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

All his days [are] painful, his labor [brings] grief, and his heart cannot rest at night. This also [is] vanity!

a time to search and a time to count as lost;
a time to keep and a time to throw away;

He hath made everything beautiful in its time: also he hath set eternity in their heart, yet so that man cannot find out the work that God hath done from the beginning even to the end.

There is one man, no more but himself alone, having neither child nor brother: yet is there no end of his careful travail, his eyes cannot be satisfied with riches. Yet, doth he not remember himself, and say, "For whom do I take such travail? For whose pleasure do I thus consume away my life?" This is also a vain and miserable thing.

And, though an enemy should prevail against one, two, might make a stand before him, - and, a threefold cord, cannot soon be broken.

A poor child being wise, is better than an old king that doteth, and cannot beware in time to come.

Just as he came naked from his mother's womb, he will leave as naked as he came; he will receive no profit from his efforts he cannot carry away even a handful.

Even if a man fathers a hundred children and lives many years -- even if he lives a long, long time, but cannot enjoy his prosperity -- even if he were to live forever -- I would say, "A stillborn child is better off than he is!"

That which is hath already been named; and what man is, is known, and that he cannot contend with him that is mightier than he.

For like the crackling of quick-burning thorns under a cooking pot, so is the laughter of the fool. This kind of folly also is useless.

In the day of prosperity, rejoice! But in the day of adversity, consider! For God made one in place of another so that mortals cannot find out what will happen {in the future}.

Do not become so very righteous, neither count thyself wise beyond measure, - wherefore shouldst thou destroy thyself?

I discovered this: More bitter than death is the kind of woman who is like a hunter's snare; her heart is like a hunter's net and her hands are like prison chains. The man who pleases God escapes her, but the sinner is captured by her.

Just as no one has power over the wind to restrain it, so no one has power over the day of his death. Just as no one can be discharged during the battle, so wickedness cannot rescue the wicked.

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 labour to seek it out, yet he shall not find it; yea further; though a wise man think to know it, yet shall he not be able to find it.

Here's another tragedy that I've observed on earth, a kind of error that comes from an overseer:

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

The fool is so worn out by a hard day's work {he cannot even find his way home at night}.
