When Adam and Eve heard God approaching, they hid among the trees--which would not have been possible before the fall. Before he committed his trespass, Adam's height was from the heavens to the earth, but afterward it was reduced to one hundred ells. Another consequence of his sin was the fear Adam felt when he heard the voice of God: before his fall it had not disquieted him in the least. Hence it was that when Adam said, "I heard Thy voice in the garden, and I was afraid," God replied, "Aforetime thou wert not afraid, and now thou art afraid?"
