베레시트 (창세기) 39:1

ויוסף הורד AND JOSEPH WAS BROUGHT DOWN — It (Scripture) now reverts to the original subject (and consequently it states ויוסף הורד “Joseph had been brought down to Egypt” before the events last mentioned); it interrupted it only in order to connect the account of the degradation of Judah (Genesis 38:1) with that of the sale of Joseph, thus suggesting that it was on account of him (i.e. Joseph — Judah’s part in the sale of Joseph — ) that they (his brothers) degraded him from his high position. A further reason why this narrative of Judah and Tamar is interpolated here is to place in juxtaposition the story of Potiphar’s wife and the story of Tamar, suggesting that just as this woman (Tamar) acted out of pure motives so also the other (Potiphar’s wife) acted out of pure motives, for she foresaw by her astrological speculations that she was destined to be the ancestress of children by him (Joseph) — but she did not know whether these children were to be hers or her daughter’s (Genesis Rabbah 85:2).

וְיוֹסֵ֖ף הוּרַ֣ד מִצְרָ֑יְמָה וַיִּקְנֵ֡הוּ פּוֹטִיפַר֩ סְרִ֨יס פַּרְעֹ֜ה שַׂ֤ר הַטַּבָּחִים֙ אִ֣ישׁ מִצְרִ֔י מִיַּד֙ הַיִּשְׁמְעֵאלִ֔ים אֲשֶׁ֥ר הוֹרִדֻ֖הוּ שָֽׁמָּה׃

And Yosef was brought down to Miżrayim; and Potifar, the chamberlain of Par῾o, captain of the guard, a Miżrian, bought him of the hands of the Yishme᾽elim, who had brought him down there.
