1: For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the LORD of hosts, that it shall leave them neither root nor branch.
2: But unto you that fear my name shall the Sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall.
3: And ye shall tread down the wicked; for they shall be ashes under the soles of your feet in the day that I shall do this, saith the LORD of hosts.
4: Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments.
5: Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD:
6: And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with 
a curse.
6. a curse = utter destruction.
