I want to know the answer to the following question:
What is the meaning of the Greek word "heos?"
All the background I'm provided with is that "The statement that Joseph "knew her not till she brought forth her first born son" (Matthew 1:25 DouayRheims) has been debated among scholars, with some saying that she did not remain a virgin and some saying that she was a perpetual virgin.". Is that enough to answer the question?
Answer: no
