Malachi 4

King James Version

See Chapter Notes:

 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.

Matthew 3:12

 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.

Chapter Notes

 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.

 Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments.

Sounds pretty clear to me!

When did this command get superceded?

 Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD:

Matthew 11:14
Matthew 17:10
Mark 9:11
John 1:21

 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.

Matthew 17:11
