In the first text on the creation (Genesis 1-2:3), the Creator is called "Elohim" (translated "God"). He creates the universe over a six-day period, creating a new feature each day: first he creates day and night; then he creates the firmament to separate the "waters above" from the "waters below"; then he separates the dry land from the water; then he creates plants on the land; then he places the Sun, Moon, and stars in the sky; then he creates swimming and flying animals; then he creates land animals; and finally he creates man and woman together, "in his own image". On the seventh day, God rests, providing the rationale for the custom of resting on Sabbath.
