Ecclesiastes 10:2

A wise man's
<02450>

heart
<03820>

[is] at his right hand
<03225>_;

but a fool's
<03684>

heart
<03820>

at his left
<08040>_.

Ecclesiastes 10:10

If the iron
<01270>

be blunt
<06949> (8765)_,

and he do not whet
<07043> (8773)

the edge
<06440>_,

then must he put
<01396> (8762)

to more strength
<02428>_:

but wisdom
<02451>

[is] profitable
<03504>

to direct
<03787> (8687)_.

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}
