Interesting. First you boast, let me check my handy dandy Hebrew, then all of a sudden I notice your use of the NIV.
So now I an going to have to check my handy dandy Authority King James Bible. This is all that I need. Not that I don't have all the others at my disposal because I most certainly do. It is just that when it comes to the translation that has stood the test of time and to the translation that has laid all others to rest in translational debates, it only makes good sense to make the KJ the rock on my stand while using the others as mere references.
And now to burst you bubble. You did such a fine job to try and convince my that firmament could mean so much more. And you are right in a sense. The only problem is your misuse of scripture or understanding of God's Holy Writ.
For there are three heavens.
In Genesis verse one, God created the heaven and the earth. This is
the first heaven or as we know it, outer space. In verse 14, God
said, let there be lights in the firmament of the heaven to divide
the day from night. and let them be for signs and for seasons, and
for days. Verse 14 thru 18 are are speaking of the heaven we know as
space.
In verse six, God said, let there be a firmament in the mist of the
waters, and let devide the waters from the waters. This is the second
heaven or as we know it today, our atmosphere. In verse 7, It says
God made the firmament and devided the waters which were under the
firmanent from the waters from the waters that were above the
firmament, and it was so. In verse eight, God called the firmament
heaven. This is the second heaven. In verse 20, it says God created
foul to fly above the earth in the open firmament of heaven.
The scripture is speaking of two heavens in Genesis, for it is
impossible for foul to fly in the heaven we know as outer space.
Proof that this is speaking of more then one heaven is found in the
first verse of Genesis two, thus the heavens and the earth were
finished. Notice, the word heaven is plurul, meaning more then one
heaven. This is not a translation error. Now if we were to put them
is the correct order, naturally, spiritual heaven would be first,
outer space second, and them the atmosphere third.
3rd) 2Cr 12:2 I knew a man in Christ above fourteen years ago,
(whether in the body, I cannot tell; or whether out of the body, I
cannot tell: God knoweth

such an one caught up to the third
heaven.
