בכור יעקב. אֲפִלּוּ בִּשְׁעַת הַקַּלְקָלָה קְרָאוֹ בְּכוֹר:

בכור יעקב JACOB’S FIRSTBORN — even when it speaks of his corrupt action Scripture calls him firstborn (Genesis Rabbah 82:11).

בכור יעקב. בְּכוֹר לַנַּחֲלָה, בְּכוֹר לָעֲבוֹדָה, בְּכוֹר לְמִנְיָן, וְלֹא נִתְּנָה בְכוֹרָה לְיוֹסֵף אֶלָּא לְעִנְיַן הַשְּׁבָטִים – שֶׁנַּעֲשָׂה לִשְׁנֵי שְׁבָטִים:

בכור יעקב JACOB’S FIRSTBORN — firstborn with regard to heritage, firstborn with regard to Divine Service (for before the Levites were appointed to minister to God the duty devolved upon the oldest son in each family), firstborn in any enumeration of the twelve tribes; for the right of a firstborn son was given to Joseph only in respect of the tribes — in that he founded two tribes (just as a firstborn son received a double portion in his father’s property) (Genesis Rabbah 82:11).
