Chasidut su Salmi 92:8

Mizmor shir le-yom ha-Shabbos, “A song for the Sabbath day,” (Psalm 92) was composed by Adam and is recited on Friday nights during the prayers that inaugurate the Shabbos. The psalm does not really describe Shabbos; it details the future age, the yom she-kullo Shabbos—an era that will be totally Shabbos.²⁹²According to Jewish tradition just as the world was created in six days and the seventh—Shabbos—was a day of rest. Similarly, humanity will have six thousand years to create a more wholesome world and then the seventh thousand will be a yom she-kullo Shabbos, a time of Shabbos (Sanhedrin 97a). Shabbos can be accepted early, and the Messiah can come before the end of the six thousand years. The psalm explains that presently fools are plentiful; they see the transient successes of evildoers and they deny God. However in the Messianic age it will be clear that Bi-froach resha’im kemo eisev, “The flowering of sinners was like plants” (it was temporal), and it was allowed, Le-hishamdam adei ad, “To destroy them for eternity” (Ps. 92:8).
