Genesis 2:17

of the tree of the knowledge of good and evil See above, on Genesis 2:9. Here only one tree is mentioned, as in Genesis 3:3; and it seems not unlikely that the mention of "the tree of life" did not belong to the main original version of the story, but was derived from a separate source.

thou shalt not eat of it In this prohibition man is apprised of another element in the discipline to which he is subjected in the garden of the Lord God. In Genesis 2:15 it is his physical and intellectual powers which are to be exercised: in this verse he receives warning of a moral discipline. His moral being is to be tested by a simple injunction for which no reason is assigned. No hardship is imposed: but a limitation to self-gratification is required. He who makes the requisition has given freely the enjoyment of everything beside. Man's character is to be tested in the simplest manner. Will he shew obedience to the Divine will and trust in the Divine goodness?

in the day that … die Literally, in the day that Adam ate of the fruit, he did not die. This is one of the minor inconsistencies in the story which are not explained for us. Either we are to assume that, in some fuller version of it, the Lord God was described as "repenting" of the sentence of immediate death, as changing His mind and sparing man in His mercy: or the words "in the day, &c." are to be regarded as metaphorical, and the doom, "thou shalt surely die," merely means "thou shalt become mortal."

We must not infer from this verse that the Lord God was considered, to have made man other than mortal. It is clear from Genesis 3:22, that man was created a mortal being. Perhaps, in one version of the story, he was intended to eat of the tree of life "and live for ever."
