Genesis 2:24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.

Genesis 4:1 Now Adam knew Eve his wife, and she conceived and bore Cain, saying, “I have gotten a man with the help of the Lord.”

Genesis 4:25 And Adam knew his wife again, and she bore a son and called his name Seth, for she said, “God has appointed for me another offspring instead of Abel, for Cain killed him.”
