네가 네 형과 아우를 접대할 때에 네 행위를 기억하고 부끄러워할 것이라 내가 그들을 네게 딸로 주려니와 네 언약으로 말미암음이 아니니라
Rashi
I am black but comely, etc. You, my friends, let me not be light in your eyes. Even if my husband has left me because of my blackness, for I am black because of the tanning of the sun, but I am comely with the shape of beautiful limbs. Though I am black like the tents of Keidar, which are blackened because of the rains, for they are always spread out in the wilderness, I am easily cleansed to become like the curtains of Shlomo. The allegory is: The congregation of Yisroel says to the nations, “I am black in my deeds [i.e., sins], but I am comely by virtue of the deeds of my ancestors, and even some of my deeds are comely. If I bear the iniquity of the [golden] calf,20According to Targum the faces of the Bnei Yisroel actually turned black like the skin of the Cushites, when they sinned with the golden calf. After they repented the blackness went away. I can offset it with the merit of the acceptance of the Torah.” [Scripture] calls the nations, “the daughters בְּנוֹת of Yerusholayim” because it is destined to become the metropolis for them all, as Yechezkeil prophesied, “I will give them to you as surrounding villages לְבָנוֹת,”21Yechezkeil 16:61. and similarly, “Ekron, and its suburbs וּבְנֹתֶיהָ.”22Yehoshua 15:45.

בכל ערי האמורי בחשבון ובכל בנותיה, for all the cities which Sichon had captured previously had become satellite tows of Cheshbon his capital. We encounter the expression בנות in this sense in Ezekiel 16,61. ונתתי אותם לך לבנות, where the word בנות means “suburbs” according to Rashi.
