Matthew 1:19-23

And her husband Joseph, since he was a righteous man and did not want to disgrace her, planned to send her away secretly.

But when he had thought this over, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take Mary as your wife; for the Child who has been conceived in her is of the Holy Spirit.

She will give birth to a Son; and you shall name Him Jesus, for He will save His people from their sins.”

Now all this took place so that what was spoken by the Lord through the prophet would be fulfilled:

“Behold, the virgin will conceive and give birth to a Son, and they shall name Him Immanuel,” which translated means, “God with us.”
