Mateus 1

18 Now the birth of Jesus Christ was in this way: when his mother Mary was going to be married to Joseph, before they came together the discovery was made that she was with child by the Holy Spirit.

19 And Joseph, her husband, being an upright man, and not desiring to make her a public example, had a mind to put her away privately.

20 But when he was giving thought to these things, an angel of the Lord came to him in a dream, saying, Joseph, son of David, have no fear of taking Mary as your wife; because that which is in her body is of the Holy Spirit.

21 And she will give birth to a son; and you will give him the name Jesus; for he will give his people salvation from their sins.
