Genesis 43:32
2 ב
וַיָּשִׂימוּ לוֹ לְבַדּוֹ, וְלָהֶם לְבַדָּם; וְלַמִּצְרִים הָאֹכְלִים אִתּוֹ, לְבַדָּם--כִּי לֹא יוּכְלוּן הַמִּצְרִים לֶאֱכֹל אֶת-הָעִבְרִים לֶחֶם, כִּי-תוֹעֵבָה הִוא לְמִצְרָיִם.
And they set on for him by himself, and for them by themselves, and for the Egyptians, that did eat with him, by themselves; because the Egyptians might not eat bread with the Hebrews; for that is an abomination unto the Egyptians. [Translation by Rabbi Steven Greenberg]
