Where does it say in Scripture that Mary was ever a virgin?

Isaiah the prophet (VII., 14) certainly predicted a supernatural and extraordinary birth of the Messiah when he wrote, “The Lord Himself shall give you a sign. Behold a virgin shall conceive and bear a son; and his name shall be called Emmanuel.” St. Luke says, “The angel Gabriel was sent from God … to a virgin . . . and the virgin’s name was Mary.” When Mary was offered the dignity of becoming the mother of the Messiah, a privilege to which any Jewish maiden would ordinarily look forward with eager desire, she urged against the prospect the fact that she had no intention of motherhood. “How shall this be done, because I know not man.” She does not refer to the past, but by using the present tense indicates her present and persevering intention. The angel assured her that her child would be due to the miraculous operation of the Holy Spirit, and that she would not be asked to forfeit the virginity she prized so highly, and then only did she consent. Luke I., 26-38. When Jesus was born Mary had none of the suffering usually associated with childbirth. The child was born miraculously, Mary herself in no way incapacitated. She herself attended to her own needs and those of the child. “She brought forth her first-born son, and wrapped him up in swaddling clothes, and laid him in a manger.” Lk. II., 7
