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. (1:18)

But 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. (1:20)

--Luke--

And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name Jesus. (1:31)

He 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: (1:32)

And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end. (1:33)

Then said Mary unto the angel, How shall this be, seeing I know not a man? (1:34)

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. (1:35)
