Mishnayos Kesuvos Perek 7 Mishnah 2

One who vows and obligates his wife, requiring her not to taste a particular type of produce, must divorce her and give her the payment of her marriage contract. Rabbi Yehuda says: If he is an Israelite, then if the vow will remain in effect for one day he may maintain her as his wife, but if it will be two days he must divorce her and give her the payment of her marriage contract. And if he is a priest, then if the vow will be in effect for two days he may maintain her; for three days he must divorce her and give her the payment of her marriage contract.
