Contradiction with Genesis 46:27
This verse states that all the souls of Jacob's house which came into Egypt were threescore and ten (70), whereas the context of Exodus 1:3 involves naming individuals among the sons of Jacob, which can be viewed differently in regards to total numbers.
Genesis 46:27: And the sons of Joseph, which were born him in Egypt, [were] two souls: all the souls of the house of Jacob, which came into Egypt, [were] threescore and ten.
