Malachi 4

[1] For behold a day is coming, heated like an oven, which shall set them on fire. And all aliens and all workers of iniquity shall be like stubble. The day which is coming shall blaze upon them, saith the Lord Almighty, and of them neither root nor branch shall be left. [2] But to you who fear my name the son of righteousness will arise with healing in his wings; and you shall go forth and leap for joy like young bullocks loosed from yokes. [3] And you shall trample down the wicked, for they will be like ashes under your feet, on the day which I make, saith the Lord Almighty.

[5] Now behold I will send you Elias the Thesbite before that great and awful day of the Lord cometh; [6] who will turn the heart of father to son and the heart of one man to another that I may not come and smite the land with utter destruction. [4] Remember the law of Moses my servant, as I gave him in charge at Choreb statutes and rules of rectitude for all Israel.
