And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.
All Commentaries on Genesis 4:16 Go To Genesis 4
Athanasius the Apostolic
AD 373
By means of righteousness we come into God’s presence, as Moses did when he entered the thick cloud where God was. On the other hand, by the practice of evil a person leaves the presence of the Lord. For example, Cain, when he killed his brother, left the Lord’s presence as far as his will was concerned.
