'Heavens' in the Bible

The earth is troubled before them and the heavens are shaking: the sun and the moon have become dark, and the stars keep back their shining:

And I will let wonders be seen in the heavens and on the earth, blood and fire and pillars of smoke.

And the Lord will be thundering from Zion, and his voice will be sounding from Jerusalem; and the heavens and the earth will be shaking: but the Lord will be a breastplate for his people and a strong place for the children of Israel.
