early in the kingdom?

(This sounds more like the day of the LORD, at the end of the tribulation.)

Ezekiel 39:9 And they that dwell in the cities of Israel shall go forth, and shall set on fire and burn the weapons, both the shields and the bucklers, the bows and the arrows, and the handstaves, and the spears, and they shall burn them with fire seven years:

12 And seven months shall the house of Israel be burying of them, that they may cleanse the land.

13 Yea, all the people of the land shall bury them; and it shall be to them a renown the day that I shall be glorified, saith the Lord GOD.

14 And they shall sever out men of continual employment, passing through the land to bury with the passengers those that remain upon the face of the earth, to cleanse it: after the end of seven months shall they search.

15 And the passengers that pass through the land, when any seeth a man’s bone, then shall he set up a sign by it, till the buriers have buried it in the valley of Hamongog.

(After the thousand year kingdom, there will be a new heaven and a new earth, so this wouldn’t be done.

Also, after the thousand year kingdom, the remaining buried bodies will all be resurrected for the great white throne judgment,

to go to the lake of fire, so bodies will no longer be buried at that point.

So, this appears to occur after the tribulation, in the early part of the kingdom.)

Ezekiel 39:4 Thou shalt fall upon the mountains of Israel, thou, and all thy bands, and the people that is with thee: I will give thee unto the ravenous birds of every sort, and to the beasts of the field to be devoured.

17 And, thou son of man, thus saith the Lord GOD; Speak unto every feathered fowl, and to every beast of the field, Assemble yourselves, and come; gather yourselves on every side to my sacrifice that I do sacrifice for you, even a great sacrifice upon the mountains of Israel, that ye may eat flesh, and drink blood.

18 Ye shall eat the flesh of the mighty, and drink the blood of the princes of the earth, of rams, of lambs, and of goats, of bullocks, all of them fatlings of Bashan.

19 And ye shall eat fat till ye be full, and drink blood till ye be drunken, of my sacrifice which I have sacrificed for you.

20 Thus ye shall be filled at my table with horses and chariots, with mighty men, and with all men of war, saith the Lord GOD.

(Again, that does not appear to line up with:)

Revelation 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.

(But, rather, it appears to line up with:)

Revelation 19:17 And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;

18 That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.

21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.

(Also, in regard to the dual fulfilment explanation:)

Ezekiel 39:25 Therefore thus saith the Lord GOD; Now will I bring again the captivity of Jacob, and have mercy upon the whole house of Israel, and will be jealous for my holy name;

26 After that they have borne their shame, and all their trespasses whereby they have trespassed against me, when they dwelt safely in their land, and none made them afraid.

27 When I have brought them again from the people, and gathered them out of their enemies’ lands, and am sanctified in them in the sight of many nations;

28 Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.

29 Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.

(This describes something after the tribulation, and not after the thousand year kingdom, especially line 29, when compared with:)

Zechariah 12:10 And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only.
