Shemot 1:1

ואלה שמות בני ישראל. אַעַ"פִּ שֶׁמְּנָאָן בְּחַיֵּיהֶם בִּשְׁמוֹתָם, חָזַר וּמְנָאָם בְּמִיתָתָם, לְהוֹדִיעַ חִבָּתָם, שֶׁנִּמְשְׁלוּ לְכוֹכָבִים, שֶׁמּוֹצִיאָם וּמַכְנִיסָם בְּמִסְפַּר וּבִשְׁמוֹתָם (שמות רבה), שֶׁנֶּ' "הַמּוֹצִיא בְמִסְפָּר צְבָאָם לְכֻלָּם בְּשֵׁם יִקְרָא" (ישעיהו מ'):

• The Torah lists the names of Jacob's children twice: when entering Egypt (Genesis 46:8-27) and again at their passing
• This repetition isn't merely historical record keeping
• As Rashi explains, it demonstrates God's special relationship with these individuals
• This repetition shows how precious these individuals were to God

AND THESE ARE THE NAMES OF …. The meaning [of the connective vav — v’eileh, (‘and’ these are) — when it would have sufficed to say, “These are the names of …,”] is that Scripture desires to reckon the subject of the exile from the time they went down to Egypt. It was then that they were the first of the exiles to go into exile, as I have explained. It is for this reason that He returns to the beginning of the subject [stated in the Book of Genesis], which is the verse, And all his seed he [Jacob] brought with him into Egypt. There it is written afterward, And these are the names of the children of Israel, who came into Egypt, etc. This is the very same verse that He repeats here. Even though they are two separate books, the narrative is connected with subjects which follow one another successively. Here, once He mentioned the children of Jacob, He adopted a concise approach to his children’s children and all of his seed [and did not mention them by name as He had done in the Book of Genesis]. Rather, He alluded to them only generally, just as He had said there, All the souls of the house of Jacob, that came into Egypt, were threescore and ten. A similar case is found in the Book of Chronicles and the Book of Ezra. The Book of Chronicles finishes with the verse: Now in the first year of Cyrus king of Persia, that the word of the Eternal by the mouth of Jeremiah might be accomplished, the Eternal stirred up the spirit of Cyrus king of Persia, that he made a proclamation throughout all his kingdom, and put it also in writing, saying: Thus saith Cyrus king of Persia, etc. The author repeated the very language of these two verses at the beginning of the Book of Ezra in order to connect the narrative. However, since they were indeed two books, he completed the first book, [i.e., the Book of Chronicles], with the events that transpired before the building of the Second Sanctuary, and he devoted the second book, [i.e., the Book of Ezra], to the events that happened from the time of the building [of that Sanctuary]. The same thing occurs in these two books, Bereshith and V’eileh Shemoth.

• The opening of "And" implies that these are in chronoligical order
  • This is important so we can remember the past.
  • Its important to know why this happened
