<04341>_.

Ecclesiastes 7:12

For wisdom
<02451>

[is] a defence
<06738>_,

[and] money
<03701>

[is] a defence
<06738>_:

but the excellency
<03504>

of knowledge
<01847>

[is, that] wisdom
<02451>

giveth life
<02421> (8762)

to them that have
<01167>

it. {defence: Heb. shadow}

And moreover
<03148>_,

because the preacher
<06953>

was wise
<02450>_,

he still taught
<03925> (8765)

the people
<05971>

knowledge
<01847>_;

yea, he gave good heed
<0239> (8765)_,

and sought out
<02713> (8765)_,

[and] set in order
<08626> (8765)

many
<07235> (8687)

proverbs
<04912>_.

{moreover...: or, the more wise the preacher was, etc}
