“These are the names of the sons of Yisrael who came to Egypt with Yaakov, each coming with his household” EXODUS 1:1 (The Israel Bible™)
Sefer Shemot starts with the letter vav (ו), which signifies the conjunction ‘and,’ thus connecting it to the end of Sefer Bereishit. In fact, the passages beginning with Shemot 1:1 and Bereishit 46:8 are practically identical, each containing a list of Yaakov’s descendants who accompanied him to Egypt. The end of Sefer Bereishit describes the children of Yaakov leaving their homeland and descending to Egypt. Sefer Shemot continues the story of the exile and the subsequent miraculous redemption, and is therefore a direct continuation of Sefer Bereishit. However, the story does not end with the conclusion of Sefer Shemot. While the slavery itself comes to an end with the exodus from Egypt, the ultimate redemption comes only with the reunification of the Children of Israel and their homeland, as described in Sefer Yehoshua.
