There's a great article and collection of other people's thoughts about seeing Jesus in the Passover, which I found HERE ON SUSAN'S BLOG. I post it here because not long ago, all I thought about the Passover was that it was a Jewish custom that meant something to the Jews when God commanded them to obey it before the great Exodus from Egypt. But after reading through the Bible itself (esp in Exodus, Isaiah) and articles like this one I share the link to, I now see God pointing to Jesus, our Passover Lamb (1 Cor 5:7) who set us free from the slavery of sin and led us out of our own Egypt.
Anyway, just thought i'd share it in case someone else is interested :)
