Dewarim 22:13 Midrasch: Ein Yaakov (Glick Edition) & Sifrei Devarim

KIDDUSHIN (Fol. 2b) We are taught in a Baraitha that R. Simon says: "Why did the Torah say (Deut. 22, 13) If any man takes a wife, and it is not written, 'If a wife is taken unto a man?' Because the custom is that a man looks after the wife, and not the reverse. This may be compared to a man who has lost something, who is looking after the loss? Surely the loser is looking for the thing he has lost."

(Devarim 22:13) "If a man take a wife, and he come upon her, and he hate her": R. Yehudah says: If he cohabits with her, he receives stripes (for libeling her [viz. Devarim 22:14]); if not, he does not receive stripes.
