Matthew 1:20-21

20But while he considered these things, behold, an angel of Adonai appeared to him in a dream, saying, “Joseph son of David, do not be afraid to take Miriam as your wife, for the Child conceived in her is from the Ruach ha-Kodesh.

21She will give birth to a son; and you shall call His name Yeshua, for He will save His people from their sins.”
