Mark 7:18

And he saith unto them ,.... With some warmth of spirit and resentment, at their stupidity:

are ye so without understanding also ? As well as others, and to such a degree; and "yet", as Matthew expresses it, Matthew 15:16 , so wretchedly stupid, and so long, and as much, as others:

do ye not perceive ? common sense will tell you,

that whatsoever thing from, without entereth into the man, it cannot defile him ; See Gill on Matthew 15:16 .
