I want to know the answer to the following question:
Who was Jacob's son?
All the background I'm provided with is that "According to the Hebrew Bible narrative, Jewish ancestry is traced back to the Biblical patriarchs such as Abraham, Isaac and Jacob, and the Biblical matriarchs Sarah, Rebecca, Leah, and Rachel, who lived in Canaan around the 18th century BCE.". Is that enough to answer the question?
Answer: no
