Malachi 4

1 For, behold, the day comes that shall burn as an oven; and all the proud, and all that do wickedly shall be stubble; and the day that comes shall burn them up, said the LORD of the hosts, that it shall leave them neither root nor branch.
2 But unto you that fear my name shall the Sun of righteousness be born, and in his wings he shall bring saving health; and ye shall go forth and jump like calves of the herd.
3 And ye shall tread down the wicked; for they shall be ashes under the soles of your feet in the day that I make, said the LORD of the hosts.
4 Remember ye the law of Moses my slave, which I commanded unto him in Horeb statutes and my rights over all Israel.
5 Behold, I send you Elijah the prophet before the coming of the great and terrible day of the LORD:
6 and he shall convert the heart of the fathers to the sons, and the heart of the sons to the fathers, lest I come and smite the earth with destruction.
