Do you not understand that whatever goes into the mouth passes into the stomach and is expelled into the sewer? Bible

“sewer.” The Greek word is aphedrōn (#856 ἀφεδρών), and it refers to a place where human waste goes: toilet, latrine, privy, sewer. By the time of Christ many of the larger cities even in Israel had some kind of public toilets and sewer systems. Often there were seats over a kind of sluice that was periodically flushed by water. Also, some cities had very developed sewer systems. Caesarea Maritima and Scythopolis are two prime examples. For example, Caesarea, on the coast of the Mediterranean Sea, had a sewer system that was flushed by the tide.
