16. He who has oznayim to hear, let him hear.
17. And when he left the multitude and entered a bais, his talmidim were asking him [about] the mashal.
18. And he says to them, Are you so lacking in binah also? Do you not have binah that it is not what is outside and entering into the ben Adam that is able to make him tameh (unclean)?
19. Because it does not enter into his lev, but into his stomach and goes out into the latrine, making all the okhel tohar [T.N. See Ro 14:14-23].
20. And Rebbe, Melech HaMoshiach was saying, It is the thing proceeding out of the ben Adam that makes him tameh.
