Quickie/Funfact: The Torah usually lists FATHER before MOTHER when the two are mentioned. Why does the Torah switch the order regarding the allowance for a Kohein to come in contact with relatives who have died? (21:2)
The Kli Yakar answers that since the Kohein's mother married into the priesthood but is not inherently a kohein, one might have thought that the kohein would not be allowed to be involved in her burial. Since the halacha regarding the mother is less obvious, she is mentioned first in this situation.

"Sheishes Yamim Taaseh Milacha U'Vayom HaShivi Shabbos Shabbason"
"On Six Days Work is done, and on the Seventh it is the Sabbath"
HaGaon R' Dov Ber Rappaport, makes a very interesting observation on the wording of this Pasuk. There are three places in the Torah when the Torah makes reference to Shabbos and calls it "Shabbos Shabbason" (Emor,VaYakel, and KiTisa) nevertheless in Parshas Yisro (Aseres Hadibros) and in Parshas V'Eschana the Torah makes no reference to Shabbos Shabbason and only calls the day "The Seventh Day, Shabbos". Why does the Torah do this?
Rav Rappaport answers that a distinction can be drawn from the Gemara in Messeches Brachos (35b). The Talmud states, "A time when Klal Yisrael does what Hashem wants of them, other people will do their work for them." We see from this adage that those people who do what Hashem asks of them every day of the week it is "Shabbos," because they have no work to do! Therefore if every day is Shabbos for them, then the real Shabbos is really Shabbos Shabason – The Sabbath of Sabbaths. According to this logic anyone who does not do the will of Hashem, and do manual labor during the week for them in fact, Shabbos is Shabbos not Shabbos Shabbason.
From here we can now properly understand why the Torah makes different references to Shabbos at different times in the Torah. In Vayakel and KiTisa the Torah is talking about those people who do the will of the Ribbono Shel Olam, therefore the Torah says "Shabbas Shabbason." In Parshas Yisro and V'Eschanan however the Torah says, "For Seven Days you shall work." In this case the Torah is referring to those people who do not do to the will of Hashem and are therefore forced to work for six days of the week and only on the Seventh do they celebrate the Holy Shabbos.HAVE A FANTASTIC SHABBOS!
