For this is the one referred to by Isaiah the prophet, saying, “The voice of one crying in the wilderness, ‘Make ready the way of the Lord, Make His paths straight!’ ”
“Behold, I am going to send My messenger, and he will prepare the way before Me. And the Lord, whom you seek, will suddenly come to His temple; and the messenger of the covenant, in whom you delight, behold, He is coming,” says Yahweh of hosts.
And he will go before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous, to make ready a people prepared for the Lord.”
