Chasidut sobre Lamentaciones 5:15

Leviticus 23,32. “from evening till evening you shall ‎observe this Sabbath of yours.” The term ‎שבת‎, which ‎primarily denotes abolition, annulment, (compare Lamentations ‎‎5,15 ‎שבת משוש לבנו נהפך לאבל מחולנו‎, “the Sabbath that used to be ‎the joy of our hearts has turned in to mourning instead of ‎dancing”) The word ‎תשבתו‎, so closely related to the word ‎שבת‎ ‎means that just as on the Sabbath we abolish the concerns of the ‎six work days preceding it, so through our repentance from one ‎evening through to the next evening, we abolish the residue of ‎our sins. All that is needed is our sincerity and our prayers.‎
