Was Jesus really born of a virgin?

¹³And he said, Hear ye now, O house of David; Is it a small thing for you to weary men, but will ye weary my God also? ¹⁴Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

²⁶And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, ²⁷To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary. ²⁸And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women. ²⁹And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be. ³⁰And the angel said unto her, Fear not, Mary: for thou hast found favour with God. ³¹And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. ³²He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: ³³And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end. ³⁴Then said Mary unto the angel, How shall this be, seeing I know not a man? ³⁵And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God. ³⁶And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. ³⁷For with God nothing shall be impossible. ³⁸And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.

¹⁸Now 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. ¹⁹Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily. ²⁰But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. ²¹And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins. ²²Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying, ²³Behold, 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. ²⁴Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife: ²⁵And knew her not till she had brought forth her firstborn son: and he called his name JESUS.
