Luke 1:11-17 … an angel of the Lord appeared to him, standing on the right side of the altar of incense. And when Zacharias saw him, he was troubled, and fear fell upon him. But the angel said to him, “Do not be afraid, Zacharias, for your prayer is heard; and your wife Elizabeth will bear you a son, and you shall call his name John. And you will have joy and gladness, and many will rejoice at his birth. For he will be great in the sight of the Lord, and shall drink neither wine nor strong drink. He will also be filled with the Holy Spirit, even from his mother’s womb. And he will turn many of the children of Israel to the Lord their God. He will also go before Him in the spirit and power of Elijah, ‘to turn the hearts of the fathers to the children,’ and the disobedient to the wisdom of the just, to make ready a people prepared for the Lord.”
Luke 1:30-35 Then the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bring forth a Son, and shall call His name Jesus. He will be great, and will be called the Son of the Highest; and the Lord God will give Him the throne of His father David. And He will reign over the house of Jacob forever, and of His kingdom there will be no end.” Then Mary said to the angel, “How can this be, since I do not know a man?” And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.
