Tree of Knowledge of Good and Evil

In the Book of Genesis the Tree of Knowledge of Good and Evil (and occasionally translated as the Tree of Conscience) was a tree in the middle of the Garden of Eden (Genesis 2:9) from which God directly forbade Adam (Eve having not yet been created) to eat (Genesis 2:17). A serpent later tempted Eve, who was aware of the prohibition, to eat the forbidden fruit from the Tree of Knowledge (Genesis 3:1-6). Adam also ate, and they became aware of their nakedness (Genesis 3:6-7). After this, in order to deny them access to the tree of life (and, hence, immortality), they were banished from the garden and forced to survive through agriculture "by the sweat of [their] face" (Genesis 3:19-24).
