(5) God called the light Day, and the darkness He called Night. And there was evening and there was morning, a first day.
All of these are derived from the Torah: Heaven and earth, as it is written: “In the beginning God created the heaven and the earth” (Genesis 1:1). Tohu and vohu, as it is written: “And the earth was unformed and void [tohu vavohu]” (Genesis 1:2). Light and darkness; darkness, as it is written: “And darkness was upon the face of the deep” (Genesis 1:2); light, as it is written: “And God said: Let there be light” (Genesis 1:3). Wind and water, as it is written: “And the wind of God hovered over the face of the waters” (Genesis 1:2). The length of day and the length of night, as it is written: “And there was evening, and there was morning, one day” (Genesis 1:5).
