The False Jews may have been fooling themselves about gaining Israel but as they turned to worship of false gods GOD abandoned them. They are still abandoned.
Zephaniah 1 quite clearly speaks of all the False Jews being hunted down and slaughtered when Jesus returns because they worship the sun and moon.
1 The word of the Lord which came unto Zephaniah the son of Cushi, the son of Gedaliah, the son of Amariah, the son of Hizkiah, in the days of Josiah the son of Amon, king of Judah.
2 I will utterly consume all things from off the land, saith the Lord.
3 I will consume man and beast; I will consume the fowls of the heaven, and the fishes of the sea, and the stumbling blocks with the wicked: and I will cut off man from off the land, saith the Lord.
4 I will also stretch out mine hand upon Judah, and upon all the inhabitants of Jerusalem; and I will cut off the remnant of Baal from this place, and the name of the Chemarims with the priests;
5 And them that worship the host of heaven upon the housetops; and them that worship and that swear by the Lord, and that swear by Malcham;
And Ezekiel 6:
Ezekiel 6 King James Version (KJV)
6 And the word of the Lord came unto me, saying,
2 Son of man, set thy face toward the mountains of Israel, and prophesy against them,
3 And say, Ye mountains of Israel, hear the word of the Lord God; Thus saith the Lord God to the mountains, and to the hills, to the rivers, and to the valleys; Behold, I, even I, will bring a sword upon you, and I will destroy your high places.
4 And your altars shall be desolate, and your images shall be broken: and I will cast down your slain men before your idols.
5 And I will lay the dead carcases of the children of Israel before their idols; and I will scatter your bones round about your altars.
6 In all your dwellingplaces the cities shall be laid waste, and the high places shall be desolate; that your altars may be laid waste and made desolate, and your idols may be broken and cease, and your images may be cut down, and your works may be abolished.
7 And the slain shall fall in the midst of you, and ye shall know that I am the Lord.
8 Yet will I leave a remnant, that ye may have some that shall escape the sword among the nations, when ye shall be scattered through the countries.
9 And they that escape of you shall remember me among the nations whither they shall be carried captives, because I am broken with their whorish heart, which hath departed from me, and with their eyes, which go a whoring after their idols: and they shall lothe themselves for the evils which they have committed in all their abominations.
10 And they shall know that I am the Lord, and that I have not said in vain that I would do this evil unto them.
Ezekiel 8:2 Then I beheld, and lo a likeness as the appearance of fire: from the appearance of his loins even downward, fire; and from his loins even upward, as the appearance of brightness, as the colour of amber.
3 And he put forth the form of an hand, and took me by a lock of mine head; and the spirit lifted me up between the earth and the heaven, and brought me in the visions of God to Jerusalem, to the door of the inner gate that looketh toward the north; where was the seat of the image of jealousy, which provoketh to jealousy.
4 And, behold, the glory of the God of Israel was there, according to the vision that I saw in the plain.
5 Then said he unto me, Son of man, lift up thine eyes now the way toward the north. So I lifted up mine eyes the way toward the north, and behold northward at the gate of the altar this image of jealousy in the entry.
14 Then he brought me to the door of the gate of the Lord's house which was toward the north; and, behold, there sat women weeping for Tammuz.
15 Then said he unto me, Hast thou seen this, O son of man? turn thee yet again, and thou shalt see greater abominations than these.
16 And he brought me into the inner court of the Lord's house, and, behold, at the door of the temple of the Lord, between the porch and the altar, were about five and twenty men, with their backs toward the temple of the Lord, and their faces toward the east; and they worshipped the sun toward the east.
Today you can see the False Jews blaspheming Jesus and thereby writing their own death certificates.
