'Heavens' in the Bible

The earth quakes before them. The heavens tremble. The sun and the moon are darkened, and the stars withdraw their shining.

I will show wonders in the heavens and in the earth: blood, fire, and pillars of smoke.

Yahweh will roar from Zion, and thunder from Jerusalem; and the heavens and the earth will shake; but Yahweh will be a refuge to his people, and a stronghold to the children of Israel.
