Genesis 3
The doctrine of the fall of man is extrapolated from the traditional Christian exegesis of Genesis 3.[15][1] According to the biblical narrative, God created Adam and Eve, the first man and woman in the chronology of the Bible.[1] God placed them in the Garden of Eden and forbade them to eat fruit from the tree of the knowledge of good and evil.[1] The serpent tempted Eve to eat fruit from the forbidden tree, which she shared with Adam, and they immediately became ashamed of their nakedness.[1] Subsequently, God banished Adam and Eve from the Garden of Eden, condemned Adam to work in order to get what he needed to live and condemned Eve to give birth in pain, and placed cherubim to guard the entrance, so that Adam and Eve would never eat from the "tree of life".
The Book of Jubilees, an apocryphal Jewish work written during the Second Temple period, gives time frames for the events that led to the fall of man by stating that the serpent convinced Eve to eat the fruit on the 17th day, of the 2nd month, in the 8th year after Adam's creation (3:17). It also states that they were removed from the Garden on the new moon of the 4th month of that year (3:33).
