她婆婆問她說：«你今天在哪裡拾取麥穗？在哪裡做工？願那眷顧你的人蒙福！»路得就把她在誰那裡做工的事告訴了婆婆，說：«我今天在那裡做工的那人，名叫波阿斯。»
Mishnah Ketubot
A yavam [who is a priest] does not allow [his sister-in-law] to eat terumah. If she had spent six months waiting for her husband and six months waiting for the yavam, or even [if she spent] all of them waiting for her husband less one day waiting for the yavam, or all of them waiting for the yavam less one day waiting for her husband, she may not eat terumah. This [was the ruling according to] the first mishnah. The court that followed afterwards ruled: a woman may not eat terumah until she has entered the bridal chamber.
