While we all begin in the water of our mothers’ wombs, at creation there were the earth’s and heaven’s waters. Water seems to have been used as a symbol for the Spirit in Genesis and Ezekiel.
Gen 1:1-2, 6-8 1 In the beginning God created the heaven and the earth. 2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. …6 And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. 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. 8 And God called the firmament Heaven. (KJV)
Later the waters from heaven would cleanse the earth via the Great Flood.
Ezekiel also seems to have water as a symbol of the Spirit.
Ez 36:25-26 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you. A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. (KJV)
