Here's the whole chapter:
Malachi 4
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
End of Mysteries,
The entire Christian Church (members of the New Covenant) is NOT SEEN NOR DESCRIBED in the First Testament. The Church is parenthetical in God's Plans. The Church will have already come and gone (died or raptured) by the time that scripture in Malachi will be fulfilled.

The perspective of Biblical history starts and ends with God’s relationship to his people, the Jews. His covenant was originally revealed to Abraham and the focus on his descendants should continue through history. At times, God blessed the children of Abraham when they were obedient, and at others, He chastised them for their rebellion, often by using other peoples as his instrument of discipline.
From an (Jewish) historical point of view, the crux of Daniel’s prophecy is Israel’s response to their Messiah. The 69 weeks would lead up to His triumphal entry into Jerusalem during the Passover in 33 a.d., when Jesus clearly presented Himself as the heir of David’s throne, the King of the Jews. Tragically, instead of acknowledging their King, the mob clamored for His crucifixion. and told Pilate they were willing put the responsibility for His blood on themselves and upon their children.
The church age should be interpreted as a parenthesis in the 70 weeks, a time when God would once again discipline his children, and use the “grafted” or “adopted” gentile Christians as his instruments of evangelism. At the end of the parenthetical period – after the Gospel had been preached to all peoples of the earth – God’s focus on the Jews would resume in the seventieth, final week.
The Messiah will come a second time – ironically in the fashion anticipated by the first-century Jews – as a warrior Messiah. They will finally “…look upon Him who they have pierced” and acknowledge His rightful ascendancy to David’s throne in Jerusalem.
When Christ returns, the Millennial Kingdom will begin and the most holy place will be anointed. This will mark the end of transgression and sin; the beginning of everlasting righteousness. There will be no further need of vision and prophecy since the King will “tabernacle,” or dwell with His people.
It should be acknowledged that “Higher Critics” claim that Daniel must have been written in the first century a.d. Why? Because a naturalistic (atheistic) world view leaves no room for supernatural prophecy. Therefore, the only explanation must be fraud. The unknown Jewish writer must have written with full knowledge of world events, and intended to mythologize the importance of his people
