The one firmament/expanse that God created and called HEAVEN.
Which is not the firmament of the heavens.
He didn't call it earth, or crust, or land because it wasn't earth, or crust, or land.
Post #270 shows why this is flatly wrong.
And He tells us what He put in the firmament (HEAVEN) ----- sun, moon, stars.
No, He tells us what He put in the "firmament of the heavens." Not the firmament.
And He tells man to have dominion over the fish that live in sea, the critters that live on land, and the birds that live in HEAVEN.
What He said was this:
Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.” - Genesis 1:28 http://www.biblegateway.com/passage/?search=Genesis1:28&version=NKJV
HEAVEN ---- the same Hebrew word used for verses 1, 8, 9, 14, 15, 17, 20.
This is misleading.
The root word, "shamayim" is what you're thinking of. However, there's a distinction made by Moses throughout the chapter that isn't easily recognizable when translated into English.
"Samayim" is what is used in verse 8, and is the only time that it is used in chapter 1.
However, "hassamayim" is used in 1:1, 9, 14, 15, 17, 20, 28, and 30. Unlike "samayim," which is just a masculine plural noun, "hassamayim" is an article.
And EVERY time "hassamayim" is used, it is used in reference to the sky, or in contrast to the earth. "Samayim" on the other hand, is used while God is working with the waters on the earth.
In none of those verses can it be said to be referring to land of the earth.
Saying it doesn't make it so.
It is most definitely biblical.
Your view is certainly traditional, but it's not correct.
Just as biblical as the virgin birth, the sun standing still for a day, sticks turning into serpents, and several other biblical events. (none of which are going to make any sense using a scientific mindset)
