Translation:Arukh ha-Shulchan…
“ What is Hanukkah? That which our Rabbis taught: On the twenty-fifth of Kislev: there are eight days of Hanukkah. One may not eulogize on them, nor to fast during them. For when Antiochus’ men entered the Holy Temple, they made impure all of the oil that was in the Sanctuary, and when the Hasmoneans came to power and defeated them, they searched but only found one jug of oil which was left with the seal of the High Priest, and there was only in it enough to light [the Menorah] for one day. A miracle happened with it, and they lit from it for eight days. ”
