Genesis 1:9,10

God said, &c. From the production, or separation from gross matter, of light and air, and the assigning them their proper places and uses in the creation, God proceeds, on the third day, to separate, put in order, and control the clement nearest to them in quality and use, fluid like them, comparatively simple, and pure, and although not elastic, yet of great power. Let the waters be gathered into one place The abyss in the bowels of the earth, Genesis 7:11, and the hollows connected therewith. Thus, instead of the confusion which existed when the earth and the water were mixed in one great mass, there was now order; and by such a separation, both were rendered useful: the earth was prepared for the habitation and support of man, and various orders of land animals, and the waters for the still more numerous tribes of living creatures, formed to abide and seek their sustenance in the seas, lakes, and rivers.
