Michael Gilleland of Laudator Temporis Acti discovers some earwax in the New Testament book of James.
I haven’t heard of this glossing of the word ῥυπαρία but maybe my ears were just plugged. This word only occurs once in the New Testament although cognate words meaning “dirt” and “filthiness” are attested. “Getting rid of the ear wax” would make sense in this passage that makes repeated use of hearing metaphors.
