Isaiah 40:21

Have ye not known
<03045> (8799)_?

have ye not heard
<08085> (8799)_?

hath it not been told
<05046> (8717)

you from the beginning
<07218>_?

have ye not understood
<0995> (8689)

from the foundations
<04146>

of the earth
<0776>_?

Isaiah 6:9

And he said
<0559> (8799)_,

Go
<03212> (8798)_,

and tell
<0559> (8804)

this people
<05971>_,

Hear
<08085> (8798)

ye indeed
<08085> (8800)_,

but understand
<0995> (8799)

not; and see
<07200> (8798)

ye indeed
<07200> (8800)_,

but perceive
<03045> (8799)

not. {indeed, but understand: or, without ceasing, etc: Heb. in hearing, etc}

Ye [are] my witnesses
<05707>_,

saith
<05002> (8803)

the LORD
<03068>_,

and my servant
<05650>

whom I have chosen
<0977> (8804)_:

that ye may know
<03045> (8799)

and believe
<0539> (8686)

me, and understand
<0995> (8799)

that I [am] he: before
<06440>

me there was no God
<0410>

formed
<03335> (8738)_,

neither shall there be after
<0310>

me. {no...: or, nothing formed of God}
