How do the heavens do this?

Jeremiah 2:11 Hath a nation changed their gods, which are yet no gods? but my people have changed their glory for that which doth not profit.

  12 Be astonished, O ye heavens, at this, and be horribly afraid, be ye very desolate, saith the LORD.

  13 For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water.

How are the heavens (plural) to be astonished, horribly afraid, and very desolate?

Who in the heavens is the LORD addressing this to?
