Parallel
Genesis 4:1
Brenton's English Septuagint · Berean Standard Bible
And Adam knew Eve his wife, and she conceived and brought forth Cain and said, I have gained a man through God.
And Adam had relations with his wife Eve, and she conceived and gave birth to Cain (note: Cain sounds like the Hebrew for acquired or brought forth.). “With the help of the LORD I have brought forth a man,” she said.
