The Gemara asks: Is that so that it is this difficult to find a match? But doesn’t Rav Yehuda say that Rav says: Forty days before the formation of the fetus a Divine Voice emerges and states: The daughter of so-and-so shall be the wife of so-and-so? Why should matching them be so difficult, since they are prepared for this from before their birth? The Gemara responds: This is not difficult. This latter statement, about predestined matches, is stated with regard to the first match; that former statement, about the difficulty of matchmaking, is stated with regard to the second match.
Rabbi Shmuel bar Naḥman says: For everything that is lost there is a substitute, except for one’s wife from youth who dies, as it is stated: “And a wife from youth, can she be rejected?” (Isaiah 54:6). Rav Yehuda taught Rav Yitzḥak, his son: A man finds calmness of spirit only from his first wife, as it is stated: “Let your fountain be blessed and have joy with the wife of your youth” (Proverbs 5:18). Rav Yitzḥak, his son, said to him: Such as whom? Rav Yehuda said to him: Such as your mother.
Rav Shmuel bar Unya says in the name of Rav: A woman is raw material, like a vessel that has not been completed, and makes a covenant, becoming truly connected, only to the one who made her a vessel through her first act of sexual intercourse, as it is stated: “For your Maker is your husband, the Lord of hosts is His name” (Isaiah 54:5).
