These were interesting verses to me in my studies...
Leviticus 15:31, "You must keep the children of Israyl aware of and separate from, things that make them unclean, so they will not die in their uncleanness BY DEFILING MY TABERNACLE which is among them."
Revelation 21:27, "But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb’s book of life."
Isayah 65
"I am sought by those who did not ask for Me; I am found by those who did not seek Me. I said: Here I am, here I am, to a nation that was not called with My Name. I have spread out My hands all the day to a rebellious people, who walk in a way which is not right, after their own thoughts; devices; A people who provoke Me to anger continually to My face; who sacrifice in gardens, and burn incense on altars of brick; Who assemble and spend the night keeping memorials for the dead, who eat swine's flesh, and the broth of abominable things; unclean foods, is in their vessels, (Isayah 66:20, "And they shall bring all your brothers from all the nations as an offering to Yahweh, on horses and in chariots and in litters and on mules and on dromedaries, to my holy mountain Jerusalem, says Yahweh, just as the Israelites bring their grain offering in a clean vessel to the house of Yahweh.") (back to Isayah 65) Who say; Stand by yourself! Do not come near me, for I am holier than you!" "These are a smoke in My nostrils, a fire that burns all the day. Behold, it is written before Me; I will not keep silence, but will recompense, even recompense into their bosom--Your iniquities and the iniquities of your fathers together, says Yahweh: who have burned incense upon the mountains, and blasphemed Me upon the hills. Therefore I will measure their former work into their bosom. This is what Yahweh says: As the new wine is found in the cluster, and one says; Do not destroy it, for a blessing is in it; so will I do for My servants' sake, that I may not destroy them all. And I will bring forth a seed out of Yaaqob, and out of Yahdah an inheritor of My mountains; and My elect will inherit it, and My servants will live there. Sharon will be a fold of flocks, and the Valley of Achor a place for herds to lie down, for My people who have sought Me. But you are those who forsake Yahweh, who forget My holy mountain, who prepare a table for that troop and who furnish a drink offering for that number. Therefore, I will number you for the sword, and you will all bow down to the slaughter, because when I called, you did not answer; when I spoke, you did not listen; but did evil in front of My eyes, and you chose that in which I did not delight. Therefore, this is what Yahweh our Father says: Behold, My servants will eat, but you will be hungry. Behold, My servants will drink, but you will be thirsty. Behold, My servants will rejoice, but you will be ashamed. Behold, My servants will sing for joy of heart, but you will cry for sorrow of heart, and wail for vexation; grief, of spirit; And the names of your gods will remain as a trap; test, to My chosen; for Yahweh our Father will slay you, but he will give His servants a Name, that will remain forever; That he who blesseth himself in the earth shall bless himself in the power of truth; and he that sweareth in the earth shall swear by the power of truth; because the former troubles are forgotten, and because they are hid from mine eyes.They have been adversaries from the beginning; therefore, they are hidden from My eyes. For behold, I create new heavens and a new earth; and the former will not be remembered, nor come into mind. But be glad and rejoice forever in what I create; for behold, I create Yerusalem as a rejoicing, and her people a joy. I will rejoice in Yerusalem, and rejoice in My people; the voice of weeping will no longer be heard in her, nor the voice of crying. No longer will there be in it an infant of only a few days, nor an old man who does not fill out his life; for the child will die a hundred years old, but the sinner being one hundred years old will be accursed; burned. They will build houses, and inhabit them; they will plant vineyards, and eat the fruit of them. They will not build, and another inhabit; they will not plant, and another eat; for as the days of a tree, so will be the days of My people, and My elect will long enjoy the work of their hands. They will not labor in vain, nor bring forth children for trouble; destruction, for they are the seed of the blessed of Yahweh, and their offspring with them. It will come to pass that before they call, I will answer; and while they are yet speaking, I will hear. The wolf and the lamb will feed together, the lion will eat straw like the ox, and dust will be the serpent's food. They will not hurt nor destroy in all My holy mountain: says Yahweh."
Isayah 66:17, "They who sanctify themselves, and purify themselves in the gardens, following after the "priest in the midst" of those who eat swine's flesh, that which is offered to gods and the rodent--will be consumed together: says Yahweh."
During the 1,000 yr reign:
Zecharyah 14:16-21, "Then it will come to pass that everyone who survives of all the nations which came against Yerusalem, will also go up from year to year to worship the King, Yahweh of hosts, by keeping the Feasts at The House of Yahweh. And it will be that if any families of the earth will not come up to Yerusalem to worship the King, Yahweh of hosts, then upon them will be no rain. family of Egypt will not come up and present themselves, they also will have no water; they will receive the same plague with which Yahweh of hosts strikes the heathen who will not come up to keep the Feasts at The House of Yahweh. This will be the punishment of Egypt and the punishment of all nations that do not go up to keep the Feasts at The House of Yahweh. In that day there will even be engraved on the bells of the horses: Qodesh La-Yahweh; Holy to Yahweh; and the pots in Yahweh's House will be like the bowls before the altar. Yes, every pot in Yerusalem and Yahdah will be holy to Yahweh of hosts, so that all who sacrifice may come and take of them, and boil the meat of the sacrifices in them. And in that day there will no longer be a Canaanite in The House of Yahweh of hosts."
