Who Was Cain and Abel's Father in Genesis 4:1–2?
Genesis 4:1–2 answers the question plainly: Cain and Abel's father is Adam, the man who knew Eve his wife, and their mother is Eve. Her own words credit Yahweh with help in the birth.
Who Was Cain's Mother? Eve in Genesis 4:1
Genesis 4:1 names Cain's mother as Eve, the woman who conceived and gave birth and who spoke of the child as help from Yahweh. The verse answers the question directly rather than leaving it to inference.
