Parshas Titzaveh: Rav Yehonoson Eibshitz The Miracle of the Ner Maaravi
The candles of the Menorah were filled with oil to last through the night. The Ner Maaravi miraculously lasted all day until the next night. Rav Yehonoson Eibushitz asks, "If so why did they bother filling it with enough oil for the night, if a few hours later it would burn through a Nes? Also, why was Chanukah such a surprising Nes if the Ner Maaravi witnessed the same Nes every day?"
He answers that daytime is a time of Chesed, and Hashem does many Nissim by day. Nighttime, however, is a time of Din and not a time of miracles. Therefore, the Ner Maaravi was filled with oil for the nighttime, and a Nes during the day was not a huge revelation. The Nes of Chanukah, which occurred at night, was a far bigger Nes than the Nes of the Ner Maaravi.
