If a man forbade his wife by vow that she should not taste a certain fruit he must divorce her and give her the Kethubah. R. Judah ruled: if he was an Israelite he may keep her [as his wife, if the vow was for] one day, [but if for] two days he must divorce her and give her the Kethubah. If, however, he was a priest he may keep her [as his wife, if the vow was for] two days [but if for] three he must divorce her and give her the Kethubah.
