The Jug of Oil and the Chanukah Miracle
The Greeks defile the Beis HaMikdash oil, but the Chashmonaim find one sealed jug, enough for a single day, which miraculously burns for eight.

From the article
The Gemara in Shabbos tells us that the Yevanim purposely defiled the oil designated for the Menorah and rendered it tamei, ritually impure. When the Bnei Yisrael retook the Beis HaMikdash, they discovered one jug of oil that was intact with the seal of the kohen gadol. This oil, which was clearly tahor, was enough oil to light the Menorah for one day. Miraculously, they were able to use the oil to light the Menorah for eight days.
