Не суй пальцы в рот!

В Шабат немного почитал из Кетубот.
Наткнулся на странный обычай класть палец кому ни попадя в рот. В частности в следующем предложении такой обычай упоминается:

R. Meir26 holding the opinion that [the husband] had himself put his finger between her teeth. But does R. Meir hold the principle, ‘He has himself put his finger between her teeth‘? Surely it was taught: If a woman made the vow of a nazirite and her husband heard of it and did not annul it, she, said R. Meir and R. Judah, has thereby put her own finger between her teeth. Therefore, if the husband wishes to annul her vow, he may do so. But if he said, ‘I do not want a wife who is in the habit of vowing’. she may be divorced without [receiving] her kethubah. R. Jose and R. Eleazar said: He has put his finger between her teeth.

Нормального коментария под рукой не оказалось. А вот сегодня под рукой оказался интернет и там я нашел весьма интересный и развернутый коментарий на этот обычай.

The case we are dealing with is where the wife pronounced the vow and the husband upheld it (there is no reason to wait and see if the wife will go to a Chacham to release her from the vow). And Rabbi Meir maintains that it is “he who put her finger between her teeth” (i.e. it is the husband’s fault because he could have annulled her vow), and therefore, she may demand to be divorced.

В этой мишне обсуждаются семейные разборки — кто кому положил палец в рот. Но мне интересно другое. Получается, что положить палец в рот — это подтверждение клятвы.
Продолжаем говорить детям, чтобы не совали пальцы в рот 🙂
