And Adam knew his wife again; and she bore a son, and called his name Seth: For God, said she, has appointed me another child instead of Abel, whom Cain slew.
All Commentaries on Genesis 4:25 Go To Genesis 4
Augustine of Hippo
AD 430
It is quite possible that when Adam was divinely inspired to say, after Seth was born, “God has given me another seed, for Abel whom Cain slew,” there is no implication here that Seth was the next born in the order of time but only that he was destined to be a fit heir in the order of holiness.
