From the moment we begin the Book of Exodus, we are already being called back into Genesis. The very first words of Parashat Shemot are: taken directly from Parashat VaYigash, during Ya’akov’s actual journey down to Egypt, where the Torah gives us a list of all the members of his household. The Ramban, in his masterful fashion, manages to quickly give both a philosophical and a literary explanation for the repetition of the verse.  As a matter of reading strategy, then, he explains that the Torah uses the callback as a device to emphasize the interconnectedness of these two books. Genesis and Exodus are thus connected not only through an ongoing storyline, but also through a set of interlocking word parallels.
