שַׁבַּ֨ת שַׁבָּת֥וֹן הִיא֙ לָכֶ֔ם וְעִנִּיתֶ֖ם אֶת־נַפְשֹׁתֵיכֶ֑ם חֻקַּ֖ת עוֹלָֽם׃
It is a sabbath of solemn rest unto you, and ye shall afflict your souls; it is a statute for ever.
Targum Jonathan on Leviticus
It is a Sabbath of rest to you: no work of business shall you do, but shall humiliate your souls. It is an everlasting statute.
