Heb 10:28 He that despised Moses' law died without mercy under two or three witnesses:

"

Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of YAHUSHUA, and for the TORAH of YAHUAH, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with YAHUSHUA for a thousand years.

Heb 10:28 Anyone who has disregarded the Torah of Mosheh dies without compassion on the witness of two or three witnesses. Heb 10:28 HeG5100 that despisedG114 Moses'G3475 lawG3551 diedG599 withoutG5565 mercyG3628 underG1909 twoG1417 orG2228 threeG5140 witnesses:G3144

2012 will happen because we have done away with The Law of Moses.
Isa 24:1
(KJV) Behold, the LORD maketh the earth empty, and maketh it waste, and turneth it upside down, and scattereth abroad the inhabitants thereof.
(KJV+) Behold,H2009 the LORDH3068 maketh the earth empty,H1238 H776 and maketh it waste,H1110 and turneth it upside down,H5753 H6440 and scattereth abroadH6327 the inhabitantsH3427 thereof.
(The Scriptures 1998+) See, יהוה is making the earth empty and making it waste, and shall overturn its surface, and shall scatter abroad its inhabitants.

Isa 24:5 For the earth has been defiled under its inhabitants, because they have transgressed the Torot1, changed2 the law, broken the everlasting covenant3. Footnotes: 1Torot - plural of Torah, teaching. 2Jer. 23:36. 3This is the only reason, according to all Scriptures, why the earth shall be burned in the day of judgment – see also 13:9, 13:11, 26:21, 66:24, Mic. 5:15, Zeph. 1:2-18.
The BIG word here is Transgressed.
The Hebrew word for Transgressed is Abar.
