12 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good.

Firmament

  

The firmament of heaven represents mutual love. The firmament, as in Genesis 1, signifies the internal man.
