החמדת. הַנְּקִיּוֹת, כְּתַרְגּוּמוֹ דָּכְיָתָא, דָּ"אַ שֶׁחָמַד אוֹתָן מִן נִמְרוֹד:
החמדות THE COSTLY GARMENTS — the clean ones, as the Targum has it, דכיתא (clean); (cf. Rashbam). Another explanation: They are called חמדות literally, coveted ones, because he had coveted them from Nimrod (who also was a hunter; cf. Genesis 10:9) (Genesis Rabbah 65:16)
אשר אתה בבית. וַהֲלֹא כַמָּה נָשִׁים הָיוּ לוֹ, וְהוּא מַפְקִיד אֵצֶל אִמּוֹ? אֶלָּא שֶׁהָיָה בָקִי בְמַעֲשֵׂיהֶן וְחוֹשְׁדָן:
אשר אתה בבית WHICH WERE WITH HER IN THE HOUSE — But he had several wives and yet he stored them with his mother! But the reason for this was that he was acquainted with their practices and was suspicious of them (Genesis 10:9) (he feared that they might steal his clothes) (Genesis Rabbah 65:16).
