I want to know the answer to the following question:
Who do Christians believe is prophesized in Isaiah 7:14?
All the background I'm provided with is that "According to Biblical scholar Bart Ehrman the Hebrew word almah, meaning young woman of childbearing age, was translated into Greek as parthenos, which only means virgin, in Isaiah 7:14, which is commonly believed by Christians to be the prophecy of the Virgin Mary referred to in Matthew 1:23.". Is that enough to answer the question?
