Book of Genesis
The first 11 chapters of Genesis tell about God. Unlike the pagans of the ancient world, the Hebrew people (later known as Israelites or Jews) believed in only one true God. Through the stories of Creation, The Great Flood and The Tower of Babel we see that God created everything, and he loves and actively sustains all his creation.
The remainder of Genesis tells the history of the patriarchs. The Jews trace their ancestry to a man named Abraham through his son Isaac and grandson Jacob. The Muslim Arabs also trace their ancestry to Abraham, through his son Ishmael.
