וְאָמְרָ֤ה אֵלַי֙ גַּם־אַתָּ֣ה שְׁתֵ֔ה וְגַ֥ם לִגְמַלֶּ֖יךָ אֶשְׁאָ֑ב הִ֣וא הָֽאִשָּׁ֔ה אֲשֶׁר־הֹכִ֥יחַ יְהוָ֖ה לְבֶן־אֲדֹנִֽי׃
그의 대답이 당신은 마시라 내가 또 당신의 약대를 위하여도 길으리라 하면 그 여자는 여호와께서 나의 주인의 아들을 위하여 정하여 주신 자가 되리이다 하며

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.
