Genesis 3:2,3

The woman said With a view to defend the conduct of her Maker toward them, against the insinuations of the tempter. We may eat of the trees of the garden Of all the trees except one. It is only concerning one that God hath said, “Ye shall not eat of it.” But when she adds, Lest ye die, it is evident her faith begins to waver, and she inclines to doubt whether God would fulfil his threatening, which was not, “Lest ye die,”

but, “In dying ye shall die;” that is, “Ye shall surely die.” She seems also to have intended to intimate, that if they died, it would not be so much through any particular interference and severity of God in executing his threatening, as through the natural, pernicious effects of the fruit, against which God had only kindly warned them.
