Rabbi S. R. Hirsch, in his “Commentary on Genesis” (i.) says: “The word ‏בראשית‎ ‘in the beginning,’ teaches that nothing preceded the act of Creation; that there was a Creatio ex nihilo. This truth forms the foundation of the faith which the Divine Law is intended to establish in our hearts. The opposite theory is the doctrine of the eternity of the substance, a theory which leaves to the Creator nothing but the function of giving form to the substance that has existed already from eternity, and which has been the basis of the heathen belief up to the present day.... The first word of the Torah dispels the darkness of this false belief; and the words, ‘The opening of thy word giveth light’ (Ps. cxix. 130), have in the Midrash correctly been applied to the word ‏בראשית‎. Everything, the matter and the form of all beings, is the result of the free will of the Creator, who continues to rule matter and form, and to determine both the natural forces and the laws of their action. For it is His free will that created matter, endowed it with certain forces, and fixed the laws by which the forces impress the different forms on it.” The idea of development and evolution is not entirely excluded from the account of the Creation. Not in one moment or in one day was the universe produced, but in six days by successive creations of a systematic order. In Mishnah Aboth (v. 1) this is expressed in the following way: “By ten words (‏מאמרות‎) the universe was created, although this could have been done by one word.” Commentators have variously attempted to explain this fact, and to show that the order observed in the Creation was determined by the nature of the things themselves. Thus Ibn Ezra believes that the successive creations were the results of the continued action of light and heat. [19] But it is by no means necessary to reconcile the Biblical account with every theory that happens to be considered by some scholar or school as the right one. There may be found in nature and in the working of the natural laws some facts analogous to certain acts of the creation; but a perfect equality of two such incongruent things as the creation from nothing and development of created beings is impossible. By forcing the text of the Bible into such harmony we deprive the account of its poetry and beauty, and weaken the force of its teaching.
