Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom you seek, shall suddenly come to his temple, even the messenger of the covenant, whom you delight in: behold, he shall come, says the LORD of hosts.
For this is he that was spoken of by the prophet Isaiah, saying, The voice of one crying in the wilderness, Prepare you the way of the Lord, make his paths straight.
