Aphedron

The Greek noun aphedron (ἀφεδρών) is a term for "latrine". The word occurs twice in the New Testament (Matthew 15:17 and Mark 7:19) but was unknown in classical texts. The Latin Vulgate rendered the term secessus 'latrine'.^[1] Wycliffe avoided the reference to a privy with "and beneath it goeth out", while Martin Luther translated the word as natürliche Gang ("natural course"),^[2] though Tyndale's "and goeth out into the draught" is clearer. Perhaps due in part to Luther's "natural course", various 18th- and 19th-century scholars assumed that the word was a euphemism for the human bowel.^[3] However, in 1901 the discovery and publication of an inscription at Pergamon^[4] confirmed that the word does, as per secessus, in fact mean "latrine".^[5]

The Mark 7:19 verse translates as "out into the aphedron, cleaning all meats" which makes no sense if the meat is still lodged in the lower intestine.^[6]
