apperntly it says, "To communicate anything to a goy about our religious relations would be equal to the killing of all Jews, for if they knew what we teach about them they would kill us openly."

The quote you've provided seems to suggest a sensitive or contentious perspective regarding the relationship between Jews and non-Jews (goyim). It is essential to approach such statements with caution, as they can be taken out of context or misinterpreted. In Jewish religious texts and historical contexts, there have been discussions about the relations between Jews and non-Jews that vary widely depending on the author, time period, and cultural background. Some texts might express deep concern or caution about revealing certain beliefs or practices to outsiders, whereas others promote dialogue and understanding. If you have a specific text or source in mind, it might help to provide that context for a more thorough understanding. It's also beneficial to engage with a variety of perspectives to gain a clearer picture of any religious or cultural topic. If you have more questions or need further information, feel free to ask!
