The meaning of the Jewish holiday is to remember God freeing the people out of Egypt, and “he” knows the remainder of the world’s slaves will be released in the coming of days.
The holiday is a bit too long for my Jewish clan, lasting a total of 8 days. However, we may embrace an annual Seder dinner with family, friends and guests for many, many years, perhaps lasting towards eternity. Just for one night, though. The reason is that it won’t be necessary to do the commandments of Exodus 12:15, Exodus 13:3, Deuteronomy 16:3, and so forth. Yet, it is a good way to remember the past, and the first night of Passover is indeed an eventful night.
