If someone touches both a corpse and utensils, or overshadows a corpse and touches utensils, the utensils are rendered unclean. If someone overshadows both a corpse and utensils, or touches a corpse and overshadows utensils, the utensils remain ritually clean. If his hand has an opening of a handbreadth, the utensils are rendered unclean. If two houses each have a half-olive volume of a corpse and he puts one hand into each, then if his hands have an opening of a handbreadth, he conveys impurity; if this is not the case, he doesn’t convey impurity.
All movable objects convey ritual impurity when they are the thickness of an ox prod. Rabbi Tarfon exclaimed that he should see the demise of his children if this isn’t a demised law that was misunderstood by someone who heard it. A farmer was passing through a cemetery with an ox prod on his shoulder, one end of which overshadowed a grave. It was declared unclean as a utensil overshadowing a corpse. Rabbi Akiva said that he could correct things so that the words of the Sages could be retained: All movable things convey ritual impurity to the one carrying them when they are as thick as an ox-prod; they themselves contract ritual impurity in any thickness and they convey impurity to other people or utensils when they have an opening of a handbreadth.
