According to the Bible:
~ There is [exactly] one 'firmament'. (one expanse which is [called] the 'firmament')
~ There is water above the 'firmament'. (not in it but above it)
~ There is water below the 'firmament'. (not in it but below it)
~ The sun, moon, and stars are in the 'firmament'. (in the upper part of it)
~ The birds fly in the 'firmament'. (in the lower part of it)
If clouds were the water above the 'firmament', then the sun, moon, and stars would be below the clouds.
However, that is not what the Bible indicates. Rather, there is water above the sun, moon, and stars.
