And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God among the trees of the garden.
All Commentaries on Genesis 3:8 Go To Genesis 3
Augustine of Hippo
AD 430
Toward evening God was walking in paradise, that is, he was coming to judge them. He was still walking in paradise before their punishment, that is, the presence of God still moved among them, when they no longer stood firm in his command. It is fitting that he comes toward evening, that is, when the sun was already setting for them, that is, when the interior light of the truth was being taken from them. They heard his voice and hid from his sight. Who hides from the sight of God but he who has abandoned him and is now beginning to love what is his own? For they now were clothed with a lie, and he who speaks a lie speaks from what is his own. This is why they are said to hide near to the tree that was in the middle of paradise, that is, near themselves who were set in the middle rank of things beneath God and above bodies. Hence they became hidden to themselves so that they might be troubled by their wretched errors after they had left the light of truth that they were not. For the human soul can be a partaker in the truth, but the truth is the immutable God above it. Hence whoever turns away from that truth and toward himself, rejoicing not in God who rules and enlightens him but rather in his own seemingly free movements, becomes dark by reason of the lie. .
