Coming and Going Backwards

  • Chullin 10b

In an effort to find a source for the rule of chazakah – relying on status quo when there is a doubt as to whether a change took place – the gemara refers to the topic of the house afflicted with tzara’at (leprosy) which can be condemned only by a kohen. At one point there is a discussion as to whether the kohen's examination can be achieved by his walking out of the house backwards in order to ensure that the contaminated area has not diminished in size.

The question is then raised as to whether walking out backwards qualifies as the departure from the house stated in the Torah. As proof that it does, the gemara cites the backward departure which the kohen gadol makes from the Holy of Holies on Yom Kippur.

Tosefot raises the question of a backwards entry into a contaminated house. The gemara in Mesechta Shavuot (17b) states that even though if one enters a contaminated house he becomes ritually impure, if he does so in backwards fashion this does not apply. Why then does this differ from the kohen gadol's departure?

The answer given by Tosefot is that a backwards entry is not considered normal, while a backwards departure like that of a disciple taking leave of his master is proper and normal.

What the Sages Say

"Is there not a difference between a doubt concerning forbidden food and a doubt concerning food which is dangerous to health?"
