7 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
7 I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
The face of the water (Genesis 1:2) signifies the knowledges of good and truth.
