On closer study, the book of Malachi turns out to be End-times aimed, focused on the restoration of Elohim's traditionally chosen people Israel.
That in itself is certainly not a strange thing, because the same can be said of the other books of the Minor Prophets, in the Bible Canon starting with the book of Hosea. But it also applies to the so-called Great Prophets: Isaiah, Jeremiah, Ezekiel and Daniel, although the latter by some is considered as belonging to the Hagiographa (Writings).
That Malachi as Elohim's proven spirit-inspired messenger also is looking ahead to End-time events can be derived from several passages, at least announcing twice YHWH Elohim's Great and dreadful day:
That YHWH Elohim, at the Times of the End, will focus again exclusively on his chosen people Israel is clear from 3:6 where He is assuring Jacob's sons [which always stand for members of ethnic Israel]: “For I, YHWH, don’t change; therefore you, sons of Jacob, are not consumed”. His love for them has not changed. Therefore, although they are strictly corrected by him, they did not come to their end.
As we again give our attention to the introductory verses, we will undoubtedly perceive that the inspired prophet protests against Israel's complaint that YHWH would have ceased to love his people. Looking back on the Jewish history of the past (almost) 2000 years, and also taking into account how the Jews since the Holocaust are looking at YHWH their Elohim - or at least many of them - one can somehow understand that they respond to the question: How did you show your love for us? Actually, their reaction is not much different from that of Job who, in his sufferings, became a prophetic type of Israel. While YHWH spoke affectionately about my ebed Job, that one also, in all his tribulations, began to doubt whether his Elohim had the better with him.
Compare Job 1:8; 32:2; 33:8-12; 42:1-8.
But notice in particular the very strong terms in the oracle when YHWH makes known his eternal judgment of Esau (Edom), and that in a prophetic setting which goes far beyond the fate of the literal nation of Edom. All that is the more striking because the Edomites as a people for a long time have disappeared from the earthly scene. After the destruction of Jerusalem in 70 AD, they ceased to exist as a people.
Concerning Esau (Edom), manifestly we will have to look behind the "Edom" of Malachi 1. Why? Not just because the Book is End-times oriented, but mainly because of Edom’s residential area is designated by God himself as the region of wickedness, and its inhabitants as the people against whom YHWH has indignation forever. Apparently, hidden things are behind ‘Edom’.
In our view, there is ample reason to believe that behind the region of wickedness, and behind the people against whom YHWH is forever indignant, unclean spirits are lurking, the fallen sons of God, those who made themselves into demons.
Compare the double judgment that would come upon 'Edom' as it is announced in the book of Obadiah, especially in the verses 18 and 21.
In the Tartarus’ situation those unclean spirits are not merely kept awaiting their final extinction at the last judgment, as many believe. In that case, Elohim after all could have better destroyed them right away when the Flood came, and they had to dematerialize. Even more than the people who perished in the Flood the Nephilim [fallen angels] deserved such a punishment.
It is certainly not surprising that God is holding the demons at his disposal with a view to still serving his purpose. As the proverb assures us: Everything YHWH has made for his purpose, yes, even the wicked for the evil day (Prov 16:4).
In Revelation, chapter 20, we find a corresponding situation: the Devil himself will shut up in the abyss for the duration of the Millennium and there he too "will be kept on hand" to the end of the thousand years to be released for a short time. And then too with the intention to serve Elohim's purpose when He pours out his final judgment upon a rebellious humanity.
In Two Thessalonians 2:8-12 the apostle has summarized how God will use the demons for the fulfilling of his purposes during the Times of the End:
NV >> 95 + 52 + 450 + 22 = 619.
● The 10 sons, respectively, according to Esther 9:7-10 .
Once he was casting out a demon, and it was mute. It happened, when the demon had gone out, the mute man spoke; and the multitudes marveled. But some of them said, “He casts out demons by Beelzebul, the prince of the demons.”… Knowing their thoughts, he said to them, “Every kingdom divided against itself is brought to desolation. A house divided against itself falls. If Satan also is divided against himself, how will his kingdom stand?”…
Earlier, Yeshua had already alluded to the complete collapse of the demon realm, namely when his disciples returned joyfully from a mission trip to announce the Messianic Empire:
The seventy-two now returned with joy, saying, "Lord, even the demons are subject to us in your name." He said to them: "I beheld [beforehand] Satan like lightning from heaven. Behold, I granted you power to tread on serpents and scorpions, and over all the power of the enemy, and nothing will harm you in any way. However, do not rejoice in the fact that the spirits are subject to you, but rejoice that your names are enrolled in heaven. "
At the final establishment of Messiah's kingdom, the demons’ empire will perish completely. As proof Yeshua beheld in advance Satan's ejection.
In Revelation 12:5-12 is announced that we may expect that event to happen immediately after the "birth" of the kingdom at the half of the last [70th] Year Week. The first act of power by the kingdom will be the purification of the holy heavens by the removal of the great Prosecutor, Satan the Devil. He will no longer be permitted to accuse the Jewish End-time saints in the sight of YHWH Elohim. Compare Job 1.
And war occurred in heaven. Michael and his angels waged war with the Dragon. And the Dragon and its angels waged war, and it had not strength, nor was found place anymore for them in heaven. And the great dragon was cast out, the ancient Serpent, who is called Devil and the Satan, the deceiver of the whole inhabited earth - he was cast into the earth, and his angels were cast with him. And I heard a loud voice in heaven, saying now occurred the salvation and the power and the kingdom of our God and the authority of his Messiah, because the accuser of our brothers, who accuses them day and night before our God was cast. And they overcame him by reason of the blood of the Lamb and by reason of the word of their testimony, and they did not love their soul unto death. The heavens and those who have their residence there, be glad for this. Woe for the earth and the sea! Because the Devil came down until you, having great fury, knowing that he has short time.
The ten horns that you saw are ten kings who have received no kingdom as yet, but they receive authority as kings, with the Beast, for one hour.These have one mind, and they give their power and authority to the beast. These will war against the Lamb, and the Lamb will overcome them, for he is Lord of lords, and King of kings.
Whereas you beheld iron mixed with miry clay; they will mingle with the seed of men; but they will not adhere to one another, one mixes to the other, just as iron does not with with miry clay. But in the days of those kings the God of heaven will set up a kingdom that will not be destroyed forever, nor will it be passed to another people. It will crush all those kingdoms and put them to an end, and it itself shall remain forever.
