Mark 7:19
Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
Because it entereth not into his heart,.... Which is the seat and fountain of all moral pollution; and if that is not defiled, no other part can be; and that that is not defiled by eating and drinking, unless in case of intemperance, is clear; because food and drink do not go into it:
but into the belly; it is taken in at the mouth, goes down the throat, and is received into the stomach, and from thence it passes through the bowels:
and goeth into the draught; aokh tyb, "the private house", as the Jews call it, without going into the heart at all:
purging all meats; that which it leaves behind, is pure and nourishing; and whatever is gross and impure, is carried with it into the draught, so that nothing remains in the man that is defiling.
