Malachi 4:4-6

4“Remember the Law of Moses, My servant, Which I commanded him in Horeb for all Israel, With the statutes and judgments.

5Behold, I will send you Elijah the prophet Before the coming of the great and dreadful day of the Lord.

6And he will turn The hearts of the fathers to the children, And the hearts of the children to their fathers, Lest I come and strike the earth with a curse.”
