Ecclesiastes 1:13

And I gave
<05414> (8804)

my heart
<03820>

to seek
<01875> (8800)

and search out
<08446> (8800)

by wisdom
<02451>

concerning all [things] that are done
<06213> (8738)

under heaven
<08064>_:

this sore
<07451>

travail
<06045>

hath God
<0430>

given
<05414> (8804)

to the sons
<01121>

of man
<0120>

to be exercised
<06031> (8800)

therewith. {to be...: or, to afflict them}

Ecclesiastes 3:11

He hath made
<06213> (8804)

every [thing] beautiful
<03303>

in his time
<06256>_:

also he hath set
<05414> (8804)

the world
<05769>

in their heart
<03820>_,

so that
<01097>

no man
<0120>

can find out
<04672> (8799)

the work
<04639>

that God
<0430>

maketh
<06213> (8804)

from the beginning
<07218>

to the end
<05490>_.

I applied
<05437> (8804)

mine heart
<03820>

to know
<03045> (8800)_,

and to search
<08446> (8800)_,

and to seek out
<01245> (8763)

wisdom
<02451>_,

and the reason
<02808>

[of things], and to know
<03045> (8800)

the wickedness
<07562>

of folly
<03689>_,

even of foolishness
<05531>

[and] madness
<01947>_:

{I applied...: Heb. I and mine heart compassed}
