וַתִּהְיֶ֜ינָה מַחְלָ֣ה תִרְצָ֗ה וְחָגְלָ֧ה וּמִלְכָּ֛ה וְנֹעָ֖ה בְּנ֣וֹת צְלָפְחָ֑ד לִבְנֵ֥י דֹדֵיהֶ֖ן לְנָשִֽׁים׃
און מַחלָה, תִּרצָה, און חָגלָה, און מִלכָּה, און נוֹעָה, די טעכטער פֿון צלָפֿחָדן, זײַנען געװאָרן פֿאַר װײַבער צו די זין פֿון זײערע פֿעטערס.
Rashi
מחלה תרצה וגו׳ MAHLA, TIRZA etc., — Here it enumerates them according to their superiority over one another in years for they were married in the order in which they were born. But everywhere else in the Bible it enumerates them according to their intelligence: This tells us that they were all equal (cf. Bava Batra 120a; Rashi on Numbers 27:1).
Ibn Ezra
Machlah, Sirtzah. Scripture mentioned them first in the order in which they were born, and now mentions them in the order that they were married.
Rabbeinu Bahya
מחלה, תרצה, “Machlah, Tirtzah;” earlier the Torah mentioned the names of these girls in the chronological order of their births, whereas here the Torah mentions them in the order of their getting married. When the Torah describes their husbands as “sons of their uncles,” this does not mean that the husbands were all brothers of one another (Ibn Ezra).
