Every Morning before the Jewish people would get there to sacrifice, a Priest would light the menorah in the Bais hamikdash. Every morning he’d get up early to light it and every night it would go out. This light symbolized God’s presence in the holy temple. They would carefully grow and prepare the olive oil using only the best olives to pour into the golden menorah.
Then the Greeks came. And after months of fighting a bloody battle, and putting an idol in the temple, they destroyed all the oil. And the light that hadn’t gone out for hundreds of years, went dark. But just as the jews were about to give up hope, they found canister of oil that hadn’t been touched to last for one more day. And the priest went up as he had done all other days and he poured the oil into the menorah and he lit it and he probably thought, “At least we’ll have it one more day”. But God made a miracle and when he came back the next day it was still lit and when he left at night, it was still let and when he came the next morning- it was still lit. And the priests fell to their knees and wept and thanked God for their faith restored. And eight days later God said “What do you think I’m made of money?”
And the priests grumbled and said “Fine fine we’ll go make more oil.”
