Genesis and Exodus are the first two books of the Bible which are said to have been composed by Moses. Genesis recounts the creation of the world and the start of the Hebrew people from Abraham's seed. Exodus goes on to record Moses' life and the Jewish people's flight from Egypt into the wilderness.
