The Hebrew in Proverbs 10:26 that is translated as “like vinegar to the teeth” or similar in English is translated in Kupsabiny as “like when bitter fruits are eaten” (source: Kupsabiny Back Translation) and in Turkmen as “pepper for the tongue” (source: Andrei S. Desnitsky in The Bible Translator 2018, p. 233ff. ).
The fathers have eaten sour grapes, and the children’s teeth are set on edge.
