‘What comes out
Of a person
Defiles a person.”
ἔλεγεν δὲ ὅτι Τὸ ἐκ τοῦ ἀνθρώπου ἐκπορευόμενον, ἐκεῖνο κοινοῖ τὸν ἄνθρωπον.
There is something similar to this in Matthew, chapter 15:18. Jesus indicated that the true defilement was what came out of a person, not what went into him. Matthew often talked about the mouth of a person, but Mark did not do that here, as he clearly explained defilement. Mark reported that Jesus said (ἔλεγεν) that what came out of a person or a man (δὲ ὅτι Τὸ ἐκ τοῦ ἀνθρώπου ἐκπορευόμενον) defiled him (ἐκεῖνο κοινοῖ τὸν ἄνθρωπον), not what went into him.
