The Greek in Ephesians 4:29 that is translated as “Let no evil talk come out of your mouths” or similar in English is translated in Muna as “In your speech, do not use rude/foul words.”

René van den Berg explains: “It is very impolite in Muna to mention someone’s mouth (wobha) or tongue (lela). The words themselves are not taboo or obscene, but in combination with a possessor they are frowned upon and should be avoided. In fact, if you want to abuse someone, you should refer to his or her mouth or tongue. The implications for translation are obvious (…). [Sometimes] ‘mouth’ was replaced by ‘lips’ (wiwi), a perfectly acceptable term, even when possessed.”
