For this is he who was spoken of by the prophet Isaiah, saying, "The voice of one crying in the wilderness: Prepare the way of the Lord, make His paths straight."
Behold, I will send My messenger, and He will clear the way before Me. And Jehovah, whom you seek, shall suddenly come to His temple, even the Angel of the Covenant, in whom you delight. Behold, He comes, says Jehovah of Hosts.
And he shall 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.
