Potiphar had had no reason to believe that Joseph could not withstand such temptation. [Pharaoh wanted the world to know that Joseph had been completely innocent of any accusation. Ed.]
ויתן לו את אסנת. וא"ת יוסף שהי' מלך איך נשא בת הדיוט. ונ"ל לפי שמתחלה הי' יוסף עבד לפוטיפר אמר בלבו אם לא אעשה רצונו לישא בתו יזלזלני וילשין אותי שהייתי עבדו אשאנה ויכבדני. ועוד י"ל שנשאה מפני שהית' מזרע יעקב כדפי' רש"י בפ' וישלח דבת דינה הית' משכם ותלה לה יעקב אבינו קמיע בצוארה והשליכה והובאה למצרים ע"י נס כדפרישית וגדלה פוטיפר בביתו ולכך נקראת על שמו כמו שמצינו גבי משה רבינו ע"ה אלה בני בתיה וגו'. וכשעבר יוסף בכל ארץ מצרים יצאו כל הנשים לראות יפיו של יוסף כדכתיב בנות צעדה עלי שור וכל אחת זורקת לו חפץ או תכשיט וזו לא היה לה מה לזרוק וזרקה לו הקמיע שהיה בצוארה ועיין בו וראה שהיא מזרעו של יעקב ונשאה: ויתן לו את אסנת, “he (Pharaoh) gave him Ossnat (as a wife) If you were to ask why Joseph who was Royalty would marry the daughter of a commoner, remember that Joseph had previously been a slave in the household of Potiphar. He therefore reasoned that if he were to refuse to marry Ossnat, the daughter of his former master, the latter would spread the word that Joseph was really a slave and that he had no business to have risen to such an exalted position. On the other hand, if he would agree and marry this woman, his former master would honour him henceforth, being proud that through this marriage he himself now had connections to the highest social circles in Egypt. There is an additional reason why he agreed to marry this woman, as she was actually a descendant of Yaakov, as Rashi has explained on Genesis, portion Vayishlach, quoting Pirke de rabbi Eliezer, chapter 38, according to which she was the daughter of Dinah from her rape by Sh’chem. According to that chapter, the angel Michael had transported that infant to Egypt where she had been adopted by Potiphar. This is why the Torah calls her the daughter of Potiphar. We find that Moses similarly was adopted by the daughter of Pharaoh, and that in Chronicles I 4,18 Calev is reported as marrying (also) Bityah-the daughter of Pharaoh, who had at the time adopted Moses. When Joseph was paraded throughout Egypt (Genesis 49,23,) and according to the Torah, all the young ladies threw flowers or jewelry at him, when Ossnat, did not have anything to throw, she threw her amulet, which she had worn around her neck at all times, at him. When Joseph looked at the inscription on it, he realised that the girl wearing it was descended from Yaakov, and he went ahead and married her.
