The Jewish festival begins tonight at sunset and ends at sunset on 16 April. If you’re not familiar with Passover, it celebrates the Israelite Exodus from Egypt. Here is the basis from Exodus for the festival:
And this day shall become a memorial for you, and you shall observe it as a festival for the L-RD, for your generations, as an eternal decree shall you observe it. For seven days you shall eat unleavened bread, but on the first day you shall remove the leaven from your homes … you shall guard the unleavened bread, because on this very day I will take you out of the land of Egypt; you shall observe this day for your generations as an eternal decree. – Exodus 12:14-17
To any Jew that comes across this, I hope this Pesach is one of great memory and great celebration.
