And God said,
Let the waters under the heaven be gathered together unto one place, and
let the dry land appear:
and it was so.
All Commentaries on Genesis 1:9 Go To Genesis 1
Augustine of Hippo
AD 430
Hence, at the words “Let the waters be gathered together, and let dry land appear,” these two things [earth and water] received their proper forms familiar to us and perceived by our senses, water being made fluid and earth solid. Of water, therefore, it is said, “Let it be gathered”; of earth, “Let it appear.” For water tends to ebb and flow, but earth remains immobile. .
