פּירוש אויף בראשית 3:23

וישלחהו , the expression here means “expelled.” It is also used in this sense in Jeremiah 16,6 שלח מעל פני, “expel from my presence.

וישלחהו, He expelled him. G’d ordered Adam to leave the garden. The expression is used in the same vein as Exodus 12,33 למהר לשלחם מן הארץ, “hastening to send them out of the country.” (Pharaoh)

וישלחהו מגן עדן, “He expelled them from Gan Eden”. He was punished in a manner similar to that of a person killing another person through neglect rather than with intent to kill, i.e. he is exiled to a city of refuge. [the whole earth other than Gan Eden in this instance. Ed.] The reason why this penalty was appropriate was that at the moment when Chavah and Adam had eaten from the tree of knowledge they had not yet possessed the knowledge of good and evil which would have made them deliberate sinners.
