Prophets and Kings page 678
In the time of the end every divine institution is to be restored. The breach made in the law at the time the Sabbath was changed by man, is to be repaired.

This "change" was prophesied by Isaiah.

Isaiah 14:12  How art thou fallen from heaven, O hallel (Hillel II), ben shawkhar! how art thou cut down to the ground, which didst weaken the nations! 13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of El: I will place the mount of the appointed times in the recesses to hide from discovery.

Friends the "mount" of the appointed times is the declaration of "The New Moon is consecrated", by the high priest of old, then the trumpet was blown announcing it, as everyone knew it was near, as it follows close to the 4th shabat of the moon. Thus Hillel II (last Sanhedrin President) was prohibited by Rome from declaring the day of The New Moon, and thus the Biblical Calendar Sabbaths, which he switched over to the Roman calendar "Saturns day" or "Saturday", which properly interpreted into modern English from Chaldee means "Satanday".

(Elohim) is true. He reigns, and will reign, notwithstanding that the church and the world have entered into a confederacy to abolish His law. Age after age Satan has been blinding men by his wiles. He has co-operated with human agencies in an effort to make falsehood truth. He has worked with intensity to defy the (Elohim) of heaven by making His law of none effect. But he has not done this; for in the ark of (Elohim) in heaven are the tables of stone upon which are written the precepts that are the foundation of His government. And the Sabbath, which (Elohim) declares to be the sign of the loyalty of His people, is placed in the bosom of the Decalogue. Its sanctity reaches into eternity; for (Elohim) declares that from one new moon to another, and from one Sabbath to another, His subjects shall come up to worship before Him in the earth made new.

Genesis 1:14 And said Elohim, Let be luminaries in the expanse of the heavens to divide between the day and the night; and let them be for a marker(strong's #226), and for appointed times(#4150), and for days and years.

Isaiah 24:5 The land also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant.

Isaiah 56:6
6 Also the sons of the stranger, that join themselves to Yahweh, to serve him, and to love the name of Y'hovah, to be his servants, every one that keepeth the sabbath from polluting it, and taketh hold of my covenant;

Jeremiah 33:25 Thus saith Y'hovah; If My covenant be not with day and night, and if I have not appointed the ordinances of heaven and earth;

Jeremiah 31:35 Thus saith Y'hovah, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divdeth the sea when the waves thereof roar; Y'hovah of hosts is His Name:

36 If those ordinances depart from before Me, saith Y'hovah, ...

Psalms 8:3 When I consider Thy heavens, the work of Thy fingers; the moon and the stars, which Thou hast ordained;

Genesis 1:14 And Elohim said, Let the lights in the firmament of the heavens separate the day from the night; and they will be for signs-(#226-owth), and for seasons-(#4150-moed-appointments), and for days, and years:

#226 'owth, oth; prob. from #225 (in the sense of appearing); a signal (lit. or fig.), as a flag, beacon, monument, omen, prodigy, evidence, etc.:--mark, miracle, (en-) sign, token.

The 4th Command, begins with #2142 zakar, zaw-kar' meaning "Mark", even day, the new moon, to consecrate it"

Jeremiah 8:8 How do you say, We are wise and the torah* is with us, lo the false pen of the scribes have falsified them and written them wrong.
* 8451 ... - especially the Decalogue...

Ezekiel 20:37- And I will cause you to pass under the rod-#7626-(Truncheon, Sceptre, MARK OF AUTHORITY), and I will  bring you into the bond of the covenant:

Early Writings page 255 "They trace down the lively oracles, but start back with trembling when they see the fourth commandment among the ten holy precepts, with a brighter light shining upon it than upon the other nine, and a halo of glory all around it" ... "Six days shalt thou labor, and do all thy work: but the seventh day is the Sabbath of Yahovah thy Elohim"

This is why "at the commencement of the time of trouble we were filled with the holy ghost and as we went forth and proclaimed the sabbath more fully", that is that it is the 7th day of YHVH's calendar, rather than the 7th day of Rome's calendar,"this enraged the nominal adventists and the church as they could not refute the sabbath truth"

They could not refute the lunar sabbath truth, because the tables of stone, having been revealed, state  "Mark even day the New Moon to consecrate it".

#2142 zakar, zaw-kar'; a prim. root; prop. to mark (so as to be recognized), i.e. to remember; by impl. to mention; also (as denom. from #2145) to be male:-- X burn [incense], X earnestly, be male, (make) mention (of), be mindful, recount, record (-er), remember, make to be remembered, bring (call, come, keep, put) to (in) remembrance, X still, think on, X well.

Spiritual Gifts. Volume 1, The Third Angel's Message Page - 164

It was represented to me that the remnant followed Y'hoshua into the Most Holy place, and beheld the ark, and the mercy-seat, and were captivated with their glory. Y'hoshua raised the cover of the ark, and behold! the tables of stone, with the ten commandments written upon them. They trace down the lively oracles; but they start back with trembling when they see the fourth commandment living among the ten holy precepts, while a brighter light shines upon it than upon the other nine, and a halo of glory is all around it. They find nothing there informing them that the Sabbath has been abolished, or changed to the first day of the week. It reads as when spoken by the mouth of Elohim in solemn and awful grandeur upon the mount, while the lightnings flashed and the thunders rolled, and when written with his own holy finger in the tables of stone. Six days shalt thou labor and do all thy work; but the seventh day is the Sabbath of Y'hovah thy Elohim. They are amazed as they behold the care taken of the ten commandments. They see them placed close by Y'hovah, overshadowed and protected by his holiness. They see that they have been trampling upon the fourth commandment of the  165   decalogue, and have observed a day handed down by the heathen and papists, instead of the day sanctified by Y'hovah. They humble themselves before Elohim, and mourn over their past transgressions.

Dear Friends,

The above quote shows us that with all the O.T. prophesies also, that the 4th command as we have it in our bibles today is not what is recorded on the tablet of stone which contains the fourth command, as He spoke It, and wrote it with His Holy Finger.
