Sforno on Genesis 2:17/ספורנו על בראשית ב׳:י״ז

1ומעץ הדעת, the tree in the middle of the garden, in close proximity to the tree of life mentioned previously (verse 9) The meaning of חיים in connection with that tree is equivalent to the meaning of the words in Deuteronomy 30:19 החיים והמות נתתי לפניך, “I have placed life and death (to choose) before you.” [we may understand this to mean that the tree of life, if its fruit were eaten, would result in life of infinite duration, whereas eating from the tree next to it would result in life being shortened. Ed.]
