A crypt that is wide at the bottom and narrow on top contains a corpse. Someone who touches the lower part remains tahor; [whereas someone who touches] the up-per part becomes tamei. [If the crypt is] wide at the top and narrow toward the bottom, someone who touches any part of it becomes tamei. [If the crypt is] the same width [from top to bottom], someone who touches any part of it becomes tamei; these are the words of R’ Eliezer. R’ Yehoshua says, [someone who touches] from a handbreadth and below remains tahor; from a handbreadth and above becomes tamei. [If the crypt] is made similar to a chest, someone who touches [anywhere on the sides] becomes tamei. [If it is made] like a gluskos, someone who touches it any-where remains tahor, except at the place where it opens.
