the earth was without form and void--or in "confusion and emptiness," as the words are rendered in Isa 34:11. This globe, at some undescribed period, having been convulsed and broken up, was a dark and watery waste for ages perhaps, till out of this chaotic state, the present fabric of the world was made to arise. the Spirit of God moved--literally, continued brooding over it, as a fowl does, when hatching eggs. The immediate agency of the Spirit, by working on the dead and discordant elements, combined, arranged, and ripened them into a state adapted for being the scene of a new creation. The account of this new creation properly begins at the end of this second verse; and the details of the process are described in the natural way an onlooker would have done, who beheld the changes that successively took place.

1:2 And the earth was {b} without form, and void; and {c} darkness [was] upon the face of the deep. And the Spirit of God {d} moved upon the face of the waters.
(b) As an unformed lump and without any creature in it: for the waters covered everything. (c) Darkness covered the deep waters, for the waters covered everything. (d) He maintained this disordered mass by his secret power.

The Spirit of God was the first Mover; He moved upon the face of the waters - He moved upon the face of the deep, as the hen gathereth her chicken under her wings, and hovers over them, to warm and cherish them, Matt. xxiii, 37 as the eagle stirs up her nest, and fluttereth over her young, ('tis the same word that is here used) Deut. xxxii, 11.
