Jacob vs Jacob

It wasn't until a couple of days ago that I actually realized that the Jacob in Singer's "The Slave" and the Jacob from the Bible were actually really similar. Ya I noticed the references mentioned comparing Wanda to Sarah but I never really made any connections. I feel sort of stupid for not noticing but I was so caught up in the story that my mind wasn't able to see anything different. Now that I have finished the book I can look back and see these connections. It also helps that a few people have presented on the idea.
