Often translated as 'feast,' the Hebrew word mo'ed is best translated 'appointed time.' (The plural is mo'edim.) The word also carries the idea of 'rehearsal,' or 'practice.' Each of God's mo'edim serves two purposes: one purpose is to remember a past event in the lives of God's people where we were blessed (memorial) and a second purpose is to rehearse or practice for an event yet to come (prophetic). The chart below lists the seven annual mo'edim, each with its' memorial and prophetic meanings.
Notice that the prophetic meanings of the first four mo'dim were fulfilled at Yeshua's first coming. However, the last three mo'edim have yet to be fulfilled. Do you think that the time for the fulfillment of these final feasts is near?
For many believers, when they first come into an understanding of the Hebrew roots of their faith, they begin to walk out this new understanding by observing God's mo'edim as laid out in this section of Leviticus. This often leads to passionate discussions with relatives and acquaintances. While it's always good to work to improve our walk with our heavenly father, it's important to remember that the commandment to love one another is a key aspect of that walk.
