The Greek in John 15:2 that is translated in English as “prune” is translated in Tenango Otomi as “care for it and take off the dry bits.” (Source: John Beekman in Notes on Translation 12, November 1964, p. 1ff.)

The most commonly German word to translate the “prune” concept is beschneiden (to cut with the goal of optimization). Since this also happens to be the word for circumcise, no German version (or dialectal version within Germany) is using this, but instead some version of “clean” (säubern or reinigen).
