“Behold, I am going to send My messenger, and he will prepare and clear the way before Me. And the Lord [the Messiah], whom you seek, will suddenly come to His temple; the Messenger of the covenant, in whom you delight, behold, He is coming,” says the Lord of hosts.

He will turn the hearts of the fathers to their children, and the hearts of the children to their fathers [a reconciliation produced by repentance], so that I will not come and strike the land with a curse [of complete destruction].”
