Luke 1:13-14, 17
But the angel said to him, “Don’t be afraid, Zacharias, because your request has been heard. Your wife, Elizabeth, will bear you a son, and you shall call his name John. You will have joy and gladness; and many will rejoice at his birth. He will 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 prepare a people prepared for the Lord.
