Thus YHVH (The Tetragrammaton), bears His "Sabbath Institution" as it is His True Weekly Cycle, His Lunar Calendar Weeks, Divinely encrypted in Leviticus 1:1 (The book of Levi, the priest).
Each Sabbath institution, both true and false, bears the name of its author, an ineffaceable mark that shows the authority of each. (clip from EGW, quote above)

The letter "vav" is a connector meaning "and" in Hebrew. It is New Moon day in this example. The letter "vav" is like a nail, joining one board to another.
The letter "vav" transitions from a declining moon to a growing moon, at new moon, and in the middle of the "Moonth" "vav" transitions from a growing moon to a declining moon. The letter "mem" is after the 29th day, "mem" represents "waters", as The Spirit hovered over the face of the waters, so we "pause" upon the Worship New Moon day from our secular activities, to Worship our Heavenly King, as well as upon the Sabbath day. There is sometimes a 30th day about every other moon.

The new moon day transitions from the previous "calendar" month of four weeks to the next "calendar" of four consecutive weeks. It is a Worship Day, see Ez. 46:3.

Vav, The Son, sees and knows what is in the darkness, He "saw" when the earth had completed one spin or revolution after "conjunction" of the "new moon", before Elohim spoke "Let there be light", on day 2 of the "moon", the first "day" of creation week, as Ellen White tells us that He in co-operation with The Father, created this world.

The seventh day sabbath is dependent upon the weekly cycle, the four weekly cycles are the four quarters of the moon you remember were on the wall calendars, kept for the farmers sake, planting according to the phases, in spite of "he shall think to change the calendar and the law(of the fourth commandment with "New Moon"). He thinks to change the law, but he can't, because there are four holy Angels, who are guarding the Ark of The Covenant, and the Tablets of Stone with the 10 commands engraved by "The Finger" of YHVH.
