20But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, #Luke 1:35for that which is conceived in her is of the Holy Spirit. 21#(Is. 7:14; 9:6, 7); Luke 1:31; 2:21And she will bring forth a Son, and you shall call His name Jesus, #Luke 2:11; John 1:29; (Acts 4:12; 5:31; 13:23, 38; Rom. 5:18, 19; Col. 1:20–23)for He will save His people from their sins.”22So all this was done that it might be fulfilled which was spoken by the Lord through the prophet, saying: 23#Is. 7:14“Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” which is translated, “God with us.”24Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, 25and did not know her till she had brought forth #Ex. 13:2; Luke 2:7, 21her firstborn Son. And he called His name Jesus.
