DRAUGHT (Mt 15:17; Mr 7:19) and DRAUGHT HOUSE (Amer. RV 'draught-house,' 2Ki 10:27) both signify a privy or closet, which in the Mishna is 'water-house.' Jehu, according to the last-cited passage, turned the temple of Baal in Samaria into public latrines.
They broke down the pillars of Baal and the house of Baal, and made it [forever unclean] a privy to this day.
Do you not see and understand that whatever goes into the mouth passes into the abdomen and so passes on into the place where discharges are deposited?
Since it does not reach and enter his heart but [only his] digestive tract, and so passes on [into the place designed to receive waste]? Thus He was making and declaring all foods [ceremonially] clean [that is, abolishing the ceremonial distinctions of the Levitical Law].
