welll...when you look at the word "virgin"in Hebrew it would be "bthuwlah" which by definition means... feminine passive participle of an unused root meaning to separate; a virgin (from her privacy); sometimes (by continuation) a bride; also (figuratively) a city or state:--maid, virgin...Doesnt say anything about not having sex.
when you look at the word in Greek it would be "parthenos" which by definition means...of unknown origin; a maiden; by implication, an unmarried daughter:--virgin...Doesnt say anything about not having sex. A virgin is an unmarried women as suggested by these definitions. They both mention "maid" or "maiden" which means an unmarried woman. Now when you read this...
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
To be espoused means give an engagement present or promise to marry married. Again, we are going to look at the Greek word since the new testament is Greek. The word in Greek is "mnesteuo" which by definition means to give a souvenir (engagement present), i.e. betroth:--espouse, the word "betroth(to promise to marry)" being the key here. It also says before they came together which means before they were married.
19Then Joseph her husband, being a just man, and not willing to make her a public example, was minded to put her away privily.
Now when you read that line it says Joseph is her husband so, lets define husband in Greek. The word in Greek is "aner" which by definition means, a primary word ; a man (properly as an individual male):--fellow, husband, man, sir. The word husband according to the Greek word did not mean that they were married, also it would only contradict what was already said above about them being "espoused" . Now mind you, in first line I posted it says she was found with the child of the Holy Ghost. So all this is taking place before they are married. The next line says "Then Joseph her husband, being a just man, and not willing to make her a public example, was minded to put her away privily." Joseph doesnt want to make her a public example of what? and he wants to put her away privily? She was already pregnant before she was married and he wanted to keep it private in other words. Now this next line says "Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us." The line I already mentioned told you she was already pregnant but she was not married, hence she was a virgin. "Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife: And knew her not till she had brought forth her firstborn son: and he called his name JESUS." Now it says he took unto him his wife and "knew" her not until she had brought forth her son, or in other words,he didnt marry her until she had her first son.
By definition the word knew, know and known doesnt not suggest sex, it is implied because when people marry they have sex.
