And God called the firmament heaven

I have memorized the first line of the Bible in Hebrew
Gen 1:1  בְּרֵאשִׁית בָּרָא אֱלֹהִים אֵת הַשָּׁמַיִם וְאֵת הָאָֽרֶץ׃

I am studying the Hebrew word "Heavens"
it is Shamayim or     שָׁמַ֫יִם


Shin שָׁ     means to consume/can be by fire

Mem  מ     means waters
Yod   יִ       means hand of God
Mem מ      waters (mayim)
ignore the vowels (ancient Hebrew had no vowels) 

Reverse Interlinear

And God		h430	אֱלֹהִים'elohiym

Let there be afirmament		h7549	רָקִיעַ raqiya`

and let it divide		h914	בָּדַל badal
the waters		h4325	מַיִם mayim
from the waters		h4325	מַיִם mayim

Here you can see that the waters were divided from the waters to make a firmament.

 God's hand (yod) divided the waters (mem) from the waters

שָׁמַיִם

sha-ma-yeem

And God called the firmament Heaven. And the evening and the morning 
were the second day.

English (KJV)   [?]		Strong's	Root Form (Hebrew)		Parsing
And God		h430	אֱלֹהִים 'elohiym
called		h7121	קָרָא qara'
the firmament		h7549	רָקִיעַ raqiya`
Heaven		h8064	שָׁמַיִם shamayim

 The Hebrew word for heaven
Shamayim = dividing the waters (mayim)
and my guess is going to be with fire(Shin)
because when I see the film I see
a lot of fire going on in the creation :) and then studying some more I found Gen1:2, verse 2.  "..the Spirit of God moved upon the face of the waters."    Well doesn't the song go something like "The Spirit of God like a fire is burning!!"

It's amazing that when I start studying it starts leading me all over the place :)
In researching Heavens and Hebrew,
I found the Joseph Smith Papers.  Here
and then I found this lovely word Hashamayim  again
