Deuteronomy 22:23
If there is a virgin pledged in marriage to a man, and another man encounters her in the city and sleeps with her,

Matthew 2:11
On coming to the house, they saw the Child with His mother Mary, and they fell down and worshiped Him. Then they opened their treasures and presented Him with gifts of gold and frankincense and myrrh.

Matthew 12:46
While Jesus was still speaking to the crowds, His mother and brothers stood outside, wanting to speak to Him.

Luke 1:27
to a virgin pledged in marriage to a man named Joseph, who was of the house of David. And the virgin's name was Mary.

Luke 1:35
The angel replied, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the Holy One to be born will be called the Son of God.

Luke 2:5
He went there to register with Mary, who was pledged to him in marriage and was expecting a child.

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.
