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).

     11. let the earth bring forth—The bare soil was clothed with verdure, and it is noticeable that the trees, plants, and grasses—the three great divisions of the vegetable kingdom here mentioned—were not called into existence in the same way as the light and the air; they were made to grow, and they grew as they do still out of the ground—not, however, by the slow process of vegetation, but through the divine power, without rain, dew, or any process of labor—sprouting up and flourishing in a single day.
