as it is written and forever remains written in the book of the words of Isaiah the prophet, “The voice of one shouting in the wilderness, ‘Prepare the way of the Lord, Make His paths straight.
He will turn the hearts of the fathers to their children, and the hearts of the children to their fathers [a reconciliation produced by repentance], so that I will not come and strike the land with a curse [of complete destruction].” [Luke 1:17]
This is the one who was mentioned by the prophet Isaiah when he said, “The voice of one shouting in the wilderness, ‘Prepare the road for the Lord, Make His highways straight (level, direct)!’ ” [Is 40:3]
