Face of the deep
The face of the deep (Genesis 1:2) signifies the lust of the unregenerate man, and the falsities that originate from it.

Genesis 1:14-19
14
God said, "Let there be lights in the expanse of sky to divide the day from the night; and let them be for signs, and for seasons, and for days and years;
15
and let them be for lights in the expanse of sky to give light on the earth;" and it was so.
16
God made the two great lights: the greater light to rule the day, and the lesser light to rule the night. He also made the stars.
17
God set them in the expanse of sky to give light to the earth,
18
and to rule over the day and over the night, and to divide the light from the darkness. God saw that it was good.
