Context: The Book of Genesis, first book of the Old Testament, gives the Hebrews' version of the creation of the universe. It describes how God created both heavens and earth, though the earth was at first without form. It was also without light, but God's Spirit moved upon the waters, and then He created light, dividing darkness from light, thus creating night and day. The first chapter of Genesis goes on to describe how the waters of the firmament were divided into the heavens and earth, and then how the dry land was created and, upon it, the vegetation and animal life. The passage is one of the most significant in the Bible historically, for the Hebrews and Christians, until relatively recent times, believed in the description, not as a legend, but as the factual account of how there came about the origin of the universe in which mankind finds itself. The Book of Genesis, one of the books called the Pentateuch, is the first of the Five Books of Moses.
