Daniel 7:15-28,
"7:15, "“As for me, Dani’ĕl, my spirit was pierced within my body, and the visions of my head alarmed me.
"7:16, "“I drew near to one of those who stood by, and asked him the certainty of all this. And he spoke to me and made known to me the interpretation of the matters:
"7:17, "These great beasts, which are four, are four sovekingdoms which rise up from the earth.
"7:18, "Then the set-apart ones of the Most High shall receive the kingdom, and possess the kingdom forever, even forever and ever.’
"7:19, "“Then I desired for certainty concerning the fourth beast, which was different from all the others, very fearsome, with its teeth of iron and its nails of bronze, which devoured, crushed, and trampled down the rest with its feet,
"7:20, "and concerning the ten horns that were on its head, and of the other horn that came up, before which three fell – this horn which had eyes and a mouth which spoke great words, whose appearance was greater than his fellows."
7:21, "“I was looking, and this horn was fighting against the set-apart ones, and was prevailing against them,"
7:22, "until the Ancient of Days came, and right-ruling was given to the set-apart ones of the Most High, and the time came and the set-apart ones took possession of the kingdom.
"7:23, "“This is what he said, ‘The fourth beast is the fourth kingdom on earth, which is different from all other kingdoms, and it devours all the earth, tramples it down and crushes it."
7:24, "And the ten horns are ten kings from this kingdom. They shall rise, and another shall rise after them, and it is different from the first ones, and it humbles three kings,"
7:25, "and it speaks words against the Most High, and it wears out the set-apart ones of the Most High, and it intends to change appointed times and law, and they are given into its hand for a time and times and half a time.
7:26, "But the Judgment shall sit, and they shall take away its rule, to cut off and to destroy, until the end."
7:27, "And the kingdom, and the rulership, and the greatness of the kingdoms under all the heavens, shall be given to the people, the set-apart ones of the Most High. His kingdom is an everlasting kingdom, and all rulerships shall serve and obey Him.’
"7:28, "“This is the end of the matter. As for me, Dani’ĕl, my thoughts greatly alarmed me, and my colour changed. And I kept the matter in my heart.”
Isaiah 66:15-24, For, behold, יהוה will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire. 16, For by fire and by his sword will יהוה plead with all flesh: and the slain of יהוה shall be many. 17, They that sanctify themselves, and purify themselves in the gardens behind one in the center (H310 אַחַר 'achar - H259 אֶחָד 'echad - H8432 תָּוֶךְ tavek, meaning followingbehind one in the centerof a congregation), eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith יהוה. 18, For I know their works and their thoughts: it shall come, that I will gather all nations and tongues; and they shall come, and see my glory. 19, And I will set a sign among them, and I will send those that escape of them unto the nations, to Tarshish, Pul, and Lud, that draw the bow, to Tubal, and Javan, to the isles afar off, that have not heard my fame, neither have seen my glory; and they shall declare my glory among the Gentiles. 20, And they shall bring all your brethren for an offering unto יהוה out of all nations upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts, to my holy mountain Jerusalem, saith יהוה, as the children of Israel bring an offering in a clean vessel into the house of יהוה. 21, And I will also take of them for priests and for Levites, saith יהוה. 22, For as the new heavens and the new earth, which I will make, shall remain before me, saith יהוה, so shall your seed and your name remain. 23, And it shall come to pass, that from one new moon to another, and from one Sabbath to another, shall all flesh come to worship before me, saith יהוה. 24, And they shall go forth, and look upon the carcasses of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorring unto all flesh."
