A garden enclosed is my sister, my spouse;
a spring dried up, a fountain sealed.
Song of Solomon 4, 12

​And Mary said to the angel: How shall this be done,
because I know not man?
Luke 1, 34

​Before she was in labor she gave birth;
before her pain came upon her she was delivered of a son.
Who ever heard of such a thing, or who ever saw the like?
Can a land be brought forth in one day,
or a nation be born in a single moment?
Yet Zion was scarcely in labor when she bore her children.
Shall I bring a mother to the point of birth,
and yet not let her child be born? says the LORD.
Or shall I who bring to birth yet close her womb?
says your God.
Isaiah 66, 7-9

​The perpetual virginity of Mary is one of the four Marian dogmas of the Catholic Church, and states that Mary, the mother of Jesus, was a virgin ante partum, in partu, et post partum--before, during and after the birth of Christ.
