וְאָמְרָ֤ה אֵלַי֙ גַּם־אַתָּ֣ה שְׁתֵ֔ה וְגַ֥ם לִגְמַלֶּ֖יךָ אֶשְׁאָ֑ב הִ֣וא הָֽאִשָּׁ֔ה אֲשֶׁר־הֹכִ֥יחַ יְהוָ֖ה לְבֶן־אֲדֹנִֽי׃
Y ella me respondiere, Bebe tú, y también para tus camellos sacaré agua: ésta sea la mujer que destinó SEÑOR para el hijo de mi señor.
Akeidat Yitzchak
When the voice from the celestial regions announces who will be married to whom in the future, the reference is to the basic compatibility of man and woman based on the endowments they have come been born with. It does not refer to accomplishments of either party since they have been born, prior to their being married. The latter is called "the second mating." Since matching two people on the basis of their respective accomplishments is a monumental task requiring supernatural insights, and there is also the difficulty of ensuring that they meet, it is described as not unlike the miracle of splitting the sea. Were this not so, one would have to assume that all man's endeavors are in vain, his prayers totally ineffective etc., everything in life preordained. The experiences of our ancestors are very illuminating in this context. Our Parshah reflects both kinds of "shiduchim," matches. More about all this in chapter 22.
