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:

defile him; (See Gill on Matthew 15:16).
