Any Bereans out there?  Ever used a Strong’s Concordance?  I have to wonder if those who bring this argument
realize that Scripture was not originally written in English.  The Hebrew word for servile in
Leviticus 23 is H5656.  
The Hebrew word for “work” in
Exodus 20:10 and Leviticus 23 is H4399.  

H5656-servile, From H5647; work of any kind: - act, bondage, + bondservant, effect, labour, ministering (-try),
office, service (-ile, -itude), tillage, use, work, X wrought.

H4399-work, From the same as H4397; properly deputyship, that is, ministry; generally employment (never servile)
or work (abstractly or concretely); also property (as the result of labor): - business, + cattle, + industrious,
occupation, (+ -pied), + officer, thing (made), use, (manner of) work ([-man], -manship).

Servile work means ANY kind of work/employment.  Work (by itself) means employment,
never servile work.  It
seems to me that servile work covers more “work” than just plain work.  But these folks never considered that, they
just looked at the English and deduced from there a false conclusion.  However, to be perfectly honest with the text,
the “work” in the fourth commandment is preceded by the word, “any”.

H3605-any, From H3634; properly the whole; hence all, any or every (in the singular only, but often in a plural
sense): - (in) all (manner, [ye]), altogether, any (manner), enough, every (one, place, thing), howsoever, as many
as, [no-] thing, ought, whatsoever, (the) whole, whoso (-ever).

So servile work means ANY kind of work/employment and any work means all MANNER of work or employment,
but
not
servile work.  Either the folks who bring this argument got it backward or these terms mean nearly the same
thing.  No work is to be done on either the annual Sabbaths or the weekly Sabbath.
22.  The Sabbath rest was different from the rest required during the ceremonial Sabbaths.
This indicates that there was a type of work they were allowed to do during the festivals that
was forbidden during the Sabbath.
