וְאֵ֨לֶּה שְׁמ֧וֹת בְּנֵֽי־יִשְׂרָאֵ֛ל הַבָּאִ֥ים מִצְרַ֖יְמָה יַעֲקֹ֣ב וּבָנָ֑יו בְּכֹ֥ר יַעֲקֹ֖ב רְאוּבֵֽן׃
און דאָס זײַנען די נעמען פֿון די קינדער פֿון ישׂראל װאָס זײַנען געקומען קײן מִצרַיִם, יעקב און זײַנע קינדער: יעקבס בכָור ראובן.
Rashi
הבאים מצרימה WHO CAME INTO EGYPT — Relative to that time when they were going to Egypt Scripture calls them “those who were coming” to Egypt (the participle) and one, therefore, need not be surprised that it does not state אשר באו “who came” (the perfect tense).
Chizkuni
ואלה שמות, “and these are the names, etc.” the Torah enumerates them once more in order to highlight the miracles of the Lord showing how seventy souls who migrated to Egypt developed into nation of at least 2,5 million souls within the space of 210 years.
Sforno
These are the names … Yaakov and his sons. Although all seventy were righteous, only Yaakov and his sons were truly worthy of being mentioned by name.
