Ecclesiastes 6:12

For who knoweth
<03045> (8802)

what [is] good
<02896>

for man
<0120>

in [this] life
<02416>_,

all
<04557>

the days
<03117>

of his vain
<01892>

life
<02416>

which he spendeth
<06213> (8799)

as a shadow
<06738>_?

for who can tell
<05046> (8686)

a man
<0120>

what shall be after
<0310>

him under the sun
<08121>_?

{all...: Heb. the number of the days of the life of his vanity}

Ecclesiastes 12:3

In the day
<03117>

when the keepers
<08104> (8802)

of the house
<01004>

shall tremble
<02111> (8799)_,

and the strong
<02428>

men
<0582>

shall bow
<05791> (8694)

themselves, and the grinders
<02912> (8802)

cease
<0988> (8804)

because they are few
<04591> (8765)_,

and those that look out
<07200> (8802)

of the windows
<0699>

be darkened
<02821> (8804)_,

{the grinders...: or, the grinders fail, because they grind little}
