Ecclesiastes 2:19

And who knoweth
<03045> (8802)

whether he shall be a wise
<02450>

[man] or a fool
<05530>_?

yet shall he have rule
<07980> (8799)

over all my labour
<05999>

wherein I have laboured
<05998> (8804)_,

and wherein I have shewed myself wise
<02449> (8804)

under the sun
<08121>_.

This [is] also vanity
<01892>_.

Ecclesiastes 3:21

Who knoweth
<03045> (8802)

the spirit
<07307>

of man
<01121> <0120>

that goeth
<05927> (8802)

upward
<04605>_,

and the spirit
<07307>

of the beast
<0929>

that goeth
<03381> (8802)

downward
<04295>

to the earth
<0776>_?

<02450>

[man]? and who knoweth
<03045> (8802)

the interpretation
<06592>

of a thing
<01697>_?

a man's
<0120>

wisdom
<02451>

maketh his face
<06440>

to shine
<0215> (8686)_,

and the boldness
<05797>

of his face
<06440>

shall be changed
<08132> (8792)_.

{the boldness: Heb. the strength}
