Wow. Thanks for the superficial analysis, Kevin.
Now try the Biblical examples. Like "she had no more children till the day she died."

Lets use your logic on Matthew 1:25.
RSV but knew her not until she had borne a son; and he called his name Jesus.
The same logic proves Joseph "knew her not" until she had born a son.
Try again.
The NAB is an approved Catholic Bible isn't it?
NAB He had no relations with her until she bore a son, (12) and he named him Jesus.
Note: (12) Until she bore a son: the evangelist is concerned to emphasize that Joseph was not responsible for the conception of Jesus. The Greek word translated "until" does not imply normal marital conduct after Jesus' birth, nor does it exclude it.
