The difference between holy and profane
This is different from this in the sense of the second. A call to conduct a test between a holy thing and a law or between a thing intended for treatment. And so: there is a blessing said with the Sabbath day in order to distinguish it from the days of illness.
("And to make a distinction between the holy and the common, and between the unclean and the clean" - and the Lord called Aaron to his office as high priest)

הַמַּבְדִּיל בֵּין קֹדֶשׁ לְחֹל
Definition (Hebrew)
זֶה בְּשׁוֹנֶה מִזֶּה בְּתַכְלִית הַשִּׁנּוּי. קְרִיאָה לַעֲרִיכַת הַבְחָנָה בֵּין קֹדֶשׁ לְחֹק אוֹ בֵּין דָּבָר חָשׁוּב לְטַפֵּל. וְכֵן: שֵׁם בְּרָכָה הַנֶּאֱמֶרֶת עִם צֵאת הַשַּׁבָּת כְּדֵי לְהַבְדִּילָהּ מִימֵי הַחֹל.
("וּלֲהַבְדִּיל בֵּין הַקֹּדֶשׁ וּבֵין הַחֹל וּבֵין הַטָּמֵא וּבֵין הַטָּהוֹר"- וַיִּקְרָא י י , ה' לְאַהֲרֹן עַל מַעֲמָדוֹ כְּכֹהֵן גָּדוֹל)
