Genesis 2:4

Day. Not that all things were made in one day: but God formed in succession; first, heaven and earth, then the ornaments of both. Every plant, &c. which on the first day did not spring up, (as water covered the surface of the earth,) on the 3d, by the command of God, without having any man to plant, or rain to water them, pushed forth luxuriantly, and manifested the power of the Creator. (Haydock) --- Thus Christ founded his Church by his own power, and still gives her increase; but requires of his ministers to co-operate with him, as a gardener must now take care of the plants which originally grew without man's aid. (Du Hamel) --- By observing that all natural means were here wanting for the production of plants, God asserts his sole right to the work, and confounds the Egyptian system, which attributed plants, &c. to the general warmth of the earth alone. (Calmet)
