9 And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. 10 God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good.
11 Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And it was so. 12 The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. 13 And there was evening, and there was morning—the third day.
John Wesley's Notes on the Old Testament
The third day's work is related in these verses; the forming the sea and the dry land, and making the earth fruitful. Hitherto the power of the Creator had been employed about the upper part of the visible world; now he descends to this lower world, designed for the children of men, both for their habitation, and their maintenance. And here we have an account of the fitting of it for both; the building of their house, and the spreading of their table.
Observe, 1. How the earth was prepared to be a habitation for man by the gathering of the waters together, and making the dry land appear. Thus, instead of that confusion which was, when earth and water were mixed in one great mass; now there is order, by such a separation as rendered them both useful.
(1.) The waters which covered the earth were ordered to retire, and to gather into one place, viz. those hollows which were fitted for their reception. The waters thus lodged in their proper place, he called Seas; for though they are many, in distant regions, yet either above ground or under ground, they have communication with each other, and so they are one, and the common receptacle of waters, into which all the rivers run.
(2.) The dry land was made to appear, and emerge out of the waters, and was called Earth.
Observe, 2. How the earth was furnished for the support of man. Present provision was made, by the immediate products of the earth, which, in obedience to God's command, was no sooner made but it became fruitful. Provision was likewise made for time to come, by the perpetuating of the several species of vegetables, every one having its seed in itself after its kind, that during the continuance of man upon the earth, food might be fetched out of the earth, for his use and benefit.
