אמר רב יהודה אמר רב ארבעים יום קודם יצירת הולד בת קול יוצאת ואומרת בת פלוני לפלוני

רש"י ד"ה מזווגין אשה לפי מעשיו. צנועה לצדיק ופרוצה לרשע:
תוספות ד"ה קודם יצירת הולד. נראה לרבי קודם יצירת הזכר בין אם לא נולדה הנקיבה עדיין בין אם נולדה:

A number of interesting observations here. First, it is interesting that the בת קול does not say פלונית לפלוני but rather בת פלוני לפלוני. One might suggest that the male is predestined to marry into a specific family but the exact identity of the daughter is not predestined. I find that to be kind of a stretch. I had thought, perhaps this is an indication that the husband should be older than the wife. In other words, the female is not identified directly because she is not yet conceived. תוספות here would seem to indicate otherwise. It is also intriguing, especially considering תוספות's approach that this declaration seems to be tied to the male. In a biblical world where males may marry more than one woman, the idea of destiny would seem more applicable to the female.

רש"י's comment, in its subtlety, is also quite telling. He does not say צנועה לצנוע or צדקת לצדיק. This would seem to be prime fodder for a schmooze on the relative roles of men and women. I don't think any elaboration is necessary at this point.
