הבאה מצרימה שבעים. פי' עם יעקב וראש הענין מוכיח כך דכתיב אלה שמות וכו'. להודיע שיעקב מן המנין עם בניו ונכלל עם בני לאה שאין בפרטן אלא ל"ב והכתוב מונה אותן ל"ג עם יעקב לפי שהוא מן המנין הראשון וממנו החל למנות מנין השבעים והכי פשטיה דקרא כל הנפש לבית יעקב הבאה מצרימה אם תרצה לידע מנינם מנה עם יעקב ותמצאם שבעים ולפי מה שפירשתי למעלה אין צריך לומר שיהא יעקב מן המנין כי הקב"ה נמנה עמהם ומשלים המנין: הבאה מצרימה שבעים, “the ones who had arrived in Egypt numbered seventy.” The Torah, in this verse, meant to include Yaakov himself. The beginning of the subject proves that this is so, as in verse 8 we have been told: “the following are the names of the Children of Israel who came to Egypt, ‘Yaakov’ and his sons, his first born son being Reuven. The word “Yaakov” in this verse is superfluous unless it was meant to include him in the count. The reason why Yaakov was included in the count with Leah’s children was that only 32 names were mentioned and he was needed to make up the number 33 at the end of that paragraph. Not only that, it was certainly fitting that the founding father should be included in the first of the four groups of people counted. If you wanted to know the precise number of Yaakov’s family in Egypt i.e. seventy, counting Joseph and his family, [assuming Joseph’s wife was Dinah’s offspring Ed.] this is how it was composed. If you wish to accept my interpretation that G–d made up the missing umber, you do not have to include Yaakov himself in the number.
