שַׁבַּ֨ת שַׁבָּת֥וֹן הִיא֙ לָכֶ֔ם וְעִנִּיתֶ֖ם אֶת־נַפְשֹׁתֵיכֶ֑ם חֻקַּ֖ת עוֹלָֽם׃
Sabbat odpoczynku to dla was, a dręczyć będziecie dusze wasze: ustawa to wieczna.
Leviticus
It is a Shabbos of complete rest for you and you shall afflict yourselves on the ninth day of the month at evening; from evening to evening you shall rest, on your day of rest.
