In Ahl HaNissim, we recite the words, “U’Leamcha Yisrael Assisa Teshua Gedola U’furkan K’Hayom Hazeh…--and for Your people You worked a great victory and salvation as this day.” What does “KeHayom Hazeh--as this day” really mean? What is the day that we are referring to?
The Sefer Baruch She’Amar (written by the Torah Temimah, Harav Boruch Halevi Epstein, z'l) suggests it means to express that although we experienced great salvation then, it was not an eternal one--which is yet to come--for just as this thing called day gets light (as it did at the time of the Chashmonaim), and then turns dark, so, too, will it get to be light once again--and it is that daylight (this time an eternal one) that we await!
