Mary the mother of Jesus and Elisabeth, John The Baptist's mother were cousins.
Then said Mary unto the angel, How shall this be, seeing I know not a man?
And 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.
And, 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.
For with God nothing shall be impossible.
And Mary arose in those days, and went into the hill country with haste, into a city of Juda;
And entered into the house of Zacharias, and saluted Elisabeth.
And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost:
And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb.
And whence is this to me, that the mother of my Lord should come to me?
For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy.
