For this is he that was spoken of by Isaiah the prophet, saying, The voice of one crying in the wilderness, Make ye ready the way of the Lord, Make his paths straight.
Behold, I send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple; and the messenger of the covenant, whom ye delight in, behold, he cometh, saith the LORD of hosts.
And he shall go before his face in the spirit and power of Elijah, to turn the hearts of the fathers to the children, and the disobedient to walk in the wisdom of the just; to make ready for the Lord a people prepared for him.
