You can read about G-d giving the feasts in Exodus 12 and Leviticus 23.  What we offer here is how Messiah Jesus (Yeshua ha Meshiach) fulfills these feasts.  What we offer is certainly not an exhaustive treatise; that would take, well, it would take a whole Bible!  The Jewish believer in Jesus has probably already discovered Jesus in the feasts.  For Gentiles, who sadly know very little about the Jewish feasts, this should be quite enlightening and exciting. For those Jews who are not yet believers, may this help to open your eyes to G-d's Truth, to G-d's Messiah.
