The Biblical concept is that, there were waters; God made the sky in the midst of the waters to separate the waters that were under the sky from the waters that were above the sky.
If the Muslims, as the media state are anti-Jews, they would have overblown and exaggerated this nasty Biblical story about the great Prophet, King David.
The Bible declares That King David has committed many great sins; e.g., 1) abandon of his business, 2) Love of ease, 3) A wandering eye, 4) commit adultery and 5) murder Bathsheba's husband who is Uriah.
