Thank you Bushmaster but I know my English thanks. IS CONVEIVING is the literal translation. Anyway even if the verse used " A VIRGIN" and "SHALL CONCEIVE" there would be no way for this to apply to Jesus for the following simple reason:
Ahaz was asked to ask for a sign because he was being attacked by the Assyrians, Now Isiaih showed up and told him that the sign would be that a boy will be born. This is the sign that can only be applied to the current time. How would it make since if the sign for Ahaz is that some boy will be born 700 years later? Read the whole story and you will find out it's not about Jesus at all. The author of Matthew is so perfect in taking things out of context in the OT.
I have discussed it in the link below:
