Ecclesiastes 8:16

When I applied my mind to know wisdom and to see the activities [of mankind] that take place upon the earth—how some men seem to sleep neither day nor night—

Psalm 127:2


It is vain for you to rise early,
To retire late,
To eat the bread of anxious labors—
For He gives [blessings] to His beloved even in his sleep.

Ecclesiastes 1:13

And I set my mind to seek and explore by [man’s] wisdom all [human activity] that has been done under heaven. It is a miserable business and a burdensome task which God has given the sons of men with which to be busy and distressed.

Ecclesiastes 2:23

For all his days his work is painful and sorrowful; even at night his mind does not rest. This too is vanity (worthless).

Genesis 31:40

This was my situation: by day the heat consumed me and by night the cold, and I could not sleep.

Ecclesiastes 4:8

There was a certain man—without a dependent, having neither a child nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “For whom do I labor and deprive myself of pleasure?” This too is vanity (a wisp of smoke, self-conceit); yes, it is a painful effort and an unhappy task.

Ecclesiastes 5:12

The sleep of a working man is sweet, whether he eats little or much; but the full stomach (greed) of the rich [who hungers for even more] will not let him sleep.

Ecclesiastes 7:25

I turned around and directed my heart to know, to investigate and to seek [skillful and godly] wisdom and the reason for things, and to know that wickedness is folly and that foolishness is madness [leading to stupidity and recklessness].

Ecclesiastes 8:7


For no one knows what will happen;
So who can tell him how and when it will happen?

Ecclesiastes 8:9

All this I have seen while applying my mind to every deed that is done under the sun. There is a time in which one man has exercised power over others to their detriment.
