Tree of the knowledge of good and evil

The tree of the knowledge of good and evil (עֵץ הַדַּעַת טוֹב וָרָע‎; Hebrew pronunciation: [Etz ha-daʿat tov wa-raʿ]) is one of two specific trees in the story of the Garden of Eden in Genesis 2–3, along with the tree of life.

Genesis 2 narrates that God places the first man and woman in a garden with trees of whose fruits they may eat, but forbids them to eat from "the tree of the knowledge of good and evil". When, in Genesis 3, a serpent seduces the woman to eat from its forbidden fruit and she also lets the man taste it, God expels them from the garden and thereby from eternal life.

The phrase in Hebrew: טוֹב וָרָע, tov wa-raʿ, literally translates as good and evil. This may be an example of the type of figure of speech known as merism, a literary device that pairs opposite terms together in order to create a general meaning, so that the phrase "good and evil" would simply imply "everything". This is seen in the Egyptian expression evil-good, which is normally employed to mean "everything". In Greek literature, Homer also uses the device when he lets Telemachus say, "I know all things, the good and the evil" (Od.20:309-10).

If tree of the knowledge of good and evil is to be understood to mean a tree whose fruit imparts knowledge of everything, this phrase does not necessarily denote a moral concept. This view is held by several scholars.

However, given the context of disobedience to God, other interpretations of the implications of this phrase also demand consideration. Robert Alter emphasizes the point that when God forbids the man to eat from that particular tree, he says that if he does so, he is "doomed to die". The Hebrew behind this is in a form regularly used in the Hebrew Bible for issuing death sentences.
