genesis 1:9 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. - Free Bible Online

      Ge 1:9-13. THIRD DAY.

      9. let the waters under the heaven be gathered together unto one place--The world was to be rendered a terraqueous globe, and this was effected by a volcanic convulsion on its surface, the upheaving of some parts, the sinking of others, and the formation of vast hollows, into which the waters impetuously rushed, as is graphically described (Ps 104:6-9) [HITCHCOCK]. Thus a large part of the earth was left "dry land," and thus were formed oceans, seas, lakes, and rivers which, though each having its own bed, or channel, are all connected with the sea (Job 38:10; Ec 1:7).
