For this is he who was spoken of by the prophet Yeshayahu, saying, “A voice of one crying in the wilderness, ‘Prepare the way of יהוה, make His paths straight.’ ”
“See, I am sending My messenger, and he shall prepare the way before Me. Then suddenly the Master you are seeking comes to His Hĕḵal, even the Messenger of the covenant, in whom you delight. See, He is coming,” said יהוה of hosts.
“And he shall go before Him in the spirit and power of Ěliyahu, ‘to turn the hearts of the fathers to the children,’ and the disobedient to the insight of the righteous, to make ready a people prepared for יהוה.”
