Genesis 1:2

2.And the earth was without form and void. I shall not be very solicitous about the exposition of these two epithets, תוהו, (tohu,) and בוהו, (bohu.) The Hebrews use them when they designate anything empty and confused, or vain, and nothing worth. Undoubtedly Moses placed them both in opposition to all those created objects which pertain to the form, the ornament and the perfection of the world. Were we now to take away, I say, from the earth all that God added after the time here alluded to, then we should have this rude and unpolished, or rather shapeless chaos. (44) Therefore I regard what he immediately subjoins that “darkness was upon the face of the abyss,” (45) as a part of that confused emptiness: because the light began to give some external appearance to the world. For the same reason he calls it the abyss and waters, since in that mass of matter nothing was solid or stable, nothing distinct.

And the Spirit of God Interpreters have wrested this passage in various ways. The opinion of some that it means the wind, is too frigid to require refutation. They who understand by it the Eternal Spirit of God, do rightly; yet all do not attain the meaning of Moses in the connection of his discourse; hence arise the various interpretations of the participle מרחפת, (merachepeth.) I will, in the first place, state what (in my judgment) Moses intended. We have already heard that before God had perfected the world it was an undigested mass; he now teaches that the power of the Spirit was necessary in order to sustain it. For this doubt might occur to the mind, how such a disorderly heap could stand; seeing that we now behold the world preserved by government, or order. (46) He therefore asserts that this mass, however confused it might be, was rendered stable, for the time, by the secret efficacy of the Spirit. Now there are two significations of the Hebrew word which suit the present place; either that the spirit moved and agitated itself over the waters, for the sake of putting forth vigor; or that He brooded over them to cherish them. (47) Inasmuch as it makes little difference in the result, whichever of these explanations is preferred, let the reader’s judgment be left free. But if that chaos required the secret inspiration of God to prevent its speedy dissolution; how could this order, so fair and distinct, subsist by itself, unless it derived strength elsewhere? Therefore, that Scripture must be fulfilled,

‘Send forth thy Spirit, and they shall be created, and thou shalt renew the face of the earth,’ (Psalms 104:30;)

so, on the other hand, as soon as the Lord takes away his Spirit, all things return to their dust and vanish away, (Psalms 104:29.)
