Testimonies Vol.  6, page 352 "But elohim has set His Seal upon His Royal Requirement. Each sabbath institution (both true and false-R&H) bears the name of its Author, an ineffaceable Mark that shows the authority of each. It is our work to lead the people to understand this. We are to show them that it is of vital consequence whether they bear the Mark of Elohim's Kingdom or the Mark of the kingdom of rebellion, for they acknowledge themselves subjects of the kingdom whose Mark they bear.

Each Sabbath institution is based upon a system of time.

YHVH's Calendar follows the lunar cycles of time.

YHVH's calendar follows creation week as "Vav", Yehoshua represents "Elohim" in Genesis chapter 1, Who created this planet according to Their council in heaven, the council that left Lucifer out of that he was jealous of not being called to, The Council between The Father and His Son Yehoshua our Messiah, for Yehoshua to Create this world, according to The Plans of The Most High.

Now, a lesson from Gematria, Hebrew letters and numerical meanings, as a calendar is basically a numbering system of days, as well as the week.

Note: In the Tetragrammaton, Yod-Hay-Vav-Hay, these letters represent, Yod=The Fater, Hay=The Mother, Vav=The Son, and Hay=The Daughter - The Human Family Created in The Image of Elohim.

One week, of 7 days, follows each letter of The Tetragrammaton, in this example of His Calendar, in Leviticus Chapter 1, showing His Sabbath is based upon His Calendar, based upon His Name. Four Letters and Four Weeks, to a lunar cycle.

Leviticus, The Priesthood Book of the Torah, begins with the Letter "Vav" which represents Yehoshua, Elohim in Genesis 1.
The Second Letter is "Yod" which Represents The Father Most High, The First Letter in the Tetragrammaton.
The next 7 letters represent the first week, ending with The Eighth letter being "Hay" the second letter of the Tetragrammaton.
Since "YHVH" inhabits eternity, He is not a "Time Dweller" and these letters here, of The Tetragrammaton do not occupy a day in this example of how "Each Sabbath institution bears the Name of It's Author, both True and False"
The next 7 letters represent the second week, ending with The Eighth Letter being "Vav" the third letter of the Tetragrammaton.
The next 7 letters represent the third week, ending with The Eighth Letter being "Hay" the fourth letter of the Tetragrammaton.
The next 7 letters represent the fourth and final week of the lunar cycle of time, called "Month" after the Moon's name, ending with the Eighth Letter "Mem" which means "Waters" reflecting back to the beginning of time when Genesis 1:2 ..."And The Spirit of Elohim moved upon the face of the waters.
This shows that after the 4th Shabat of the moon, the one or two days of the New Moon, that we are also in a mode of time outside of the "Six working days", showing The Spirit "moved" on Conjunction day of the Moon, before the "six work days"
"Mark even day, Ha Kodesh, to Quodesh It." in stone, not, "Remember the Sabbath Day to keep it holy" "Zawkar eth yom ha kodesh la quodesh oo" means "mark even-namely day the new moon to consecrate it" meaning "blow up the trumpet in the new moon, the covered moon, on our solemn assembly day"

Now the False Sabbath, is Saturday which literally means "Satan day", as "Satyr" in old chaldee means "Satan". As Saturday is a pagan term, with no regular calendar of monthly days for the week to cycle according to. To accept this falsehood is to accept that Our Creator is dis-organized, with two conflicting calendars, with pieces of the puzzle not joining together as Ezekiel 46:3 proves that logic, a door is closed or open, can't be in both conditions at the same time.
