'Sky' in the Bible

and the stars of the sky fell to the earth, as a fig tree casts its unripe figs when shaken by a great wind.

The sky was split apart like a scroll when it is rolled up, and every mountain and island were moved out of their places.

These have the power to shut up the sky, so that rain will not fall during the days of their prophesying; and they have power over the waters to turn them into blood, and to strike the earth with every plague, as often as they desire.
