The point here is that if you put 10 scholars in the same room, they will have 10 different opinions regarding some of
the more difficult passages in Scripture.  So, how do you tell which one(s) are correct, or the most correct?

Simple.  
To the law [Torah] and to the testimony [of the prophets]: if they speak not according to this word, it is
because there is no light in them
.  Isaiah 8:20.  The scholar or work that agrees with Scripture is telling the truth.  
Everyone else is telling a various shade of a lie.

Genesis 1:14 says that the two great lights would be for signs, seasons (Hebrew word, Mo’edim--appointed times,
set feasts), days and years.  Thus the calendar of Yah is by the two great luminaries in the heavens.

Psalm 104:19 says that the moon will regulate the seasons (Hebrew, Mo’edim--appointed times, set feasts).  
Leviticus 23:1-3 shows the weekly Sabbath to be the first feast (SAME Hebrew word, Mo’edim--appointed times,
set feasts).  

Genesis 1:14 also says that the two great lights (the sun or the moon) would be for signs, seasons, days and
years.  This is the Hebrew word
owth, which means signal or beacon.  Exodus 31:13, Ezekiel 20:12 and 20:20 all
agree that the Sabbath is a sign, using the SAME Hebrew word found in
Genesis 1:14, owth.

So, let's put the two great luminaries to the test.  Can you go outside, look at the sun on a satyrday morning and tell
if it is the Sabbath?  No.  Can you tell that it is the seventh day of the week?  No.  Can the sun even tell you that it is
satyrday?  NO!  So, what's the problem?  You are looking at the wrong light.

This alone is enough to prove that the Sabbath is regulated by the moon.  So you can safely tell the objector that we
found (and used) Scripture first.  Actually, I never went seeking the support of the historical evidence until someone
asked me if there was any.  I had no idea and really did not care.  Scripture says that the Sabbath is by the moon,
who needs the support of scholars?  But I figured it might be interesting and/or educational, so I went looking and
found some authors whose conclusions line up with Scripture.  So the scholars we quote are not historical-critical as
one would suppose.  Much to the consternation of our detractors, these scholars are Scriptural-accurate.  Here is a
small sample...

“The New Moon is still, and the Sabbath originally was, dependent upon the lunar cycle.”
Universal Jewish
Encyclopedia, p. 410
.  No quote can be clearer than this.

“In the time of the earliest prophets, the New Moon stood in the same line with another lunar observance, the
Sabbath.  Ezekiel, who curiously enough frequently dates his prophecies on the New Moon … describes the gate of
the inner court of the (new) temple looking eastward as kept shut for the six working days, but opened on the
Sabbath and the New Moon.”  
Scribner's Dictionary of the Bible (1898 edit.), p. 521

“The Hebrew month is a lunar month and the quarter of this period—one phase of the moon—appears to have
determined the week of seven days.”
Encyclopedia Biblica, p. 4780.  

“…The [early] Hebrews employed lunar seven-day weeks…which ended with special observances on the seventh
day but none the less were tied to the moon’s course.”  
Hutton Webster, in his book, Rest Days, page 254.

“… the custom of celebrating the Sabbath every 7th day, irrespective of the relationship of the day to the moon’s
phases, led to a complete separation from the ancient view of the Sabbath...”  
Encyclopedia Biblica, (1899 edit.), p.
4179.   

“With the development of the importance of the Sabbath as a day of consecration and the emphasis laid upon the
significant number seven, the week became more and more divorced from its lunar connection...”  
Universal Jewish
Encyclopedia: Vol. 10, 1943 edit. Article, "Week," p. 482.

“The four quarters of the moon supply an obvious division of the month...it is most significant that in the older parts
of the Hebrew scriptures the new moon and the Sabbath are almost invariably mentioned together.  The [lunar]
month is beyond question an old sacred division of time common to all the semites; even the Arabs, who received
the week at quite a late period from the Syrians, greeted the New Moon with religious acclamations. …  We cannot
tell [exactly] when the Sabbath became disassociated from the month.”  
Encyclopedia Biblica, 1899 edit., pp. 4178-
4179.

critical scholars in the 19th and early 20th centuries who assert erroneous positions.
